git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "Here is the bulk of GPIO changes for v4.5. Notably there are big refactorings mostly by myself, aimed at getting the gpio_chip into a shape that makes me believe I can proceed to preserve state for a proper userspace ABI (character device) that has already been proposed once, but resulted in the feedback that I need to go back and restructure stuff. So I've been restructuring stuff. On the way I ran into brokenness (return code from the get_value() callback) and had to fix it. Also, refactored generic GPIO to be simpler. Some of that is still waiting to trickle down from the subsystems all over the kernel that provide random gpio_chips, I've touched every single GPIO driver in the kernel now, oh man I didn't know I was responsible for so much... Apart from that we're churning along as usual. I took some effort to test and retest so it should merge nicely and we shook out a couple of bugs in -next. Infrastructural changes: - In struct gpio_chip, rename the .dev node to .parent to better reflect the fact that this is not the GPIO struct device abstraction. We will add that soon so this would be totallt confusing. - It was noted that the driver .get_value() callbacks was sometimes reporting negative -ERR values to the gpiolib core, expecting them to be propagated to consumer gpiod_get_value() and gpio_get_value() calls. This was not happening, so as there was a mess of drivers returning negative errors and some returning "anything else than zero" to indicate that a line was active. As some would have bit 31 set to indicate "line active" it clashed with negative error codes. This is fixed by the largeish series clamping values in all drivers with !!value to [0,1] and then augmenting the code to propagate error codes to consumers. (Includes some ACKed patches in other subsystems.) - Add a void *data pointer to struct gpio_chip. The container_of() design pattern is indeed very nice, but we want to reform the struct gpio_chip to be a non-volative, stateless business, and keep states internal to the gpiolib to be able to hold on to the state when adding a proper userspace ABI (character device) further down the road. To achieve this, drivers need a handle at the internal state that is not dependent on their struct gpio_chip() so we add gpiochip_add_data() and gpiochip_get_data() following the pattern of many other subsystems. All the "use gpiochip data pointer" patches transforms drivers to this scheme. - The Generic GPIO chip header has been merged into the general <linux/gpio/driver.h> header, and the custom header for that removed. Instead of having a separate mm_gpio_chip struct for these generic drivers, merge that into struct gpio_chip, simplifying the code and removing the need for separate and confusing includes. Misc improvements: - Stabilize the way GPIOs are looked up from the ACPI legacy specification. - Incremental driver features for PXA, PCA953X, Lantiq (patches from the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48 New drivers: - Add a GPIO chip to the ALSA SoC AC97 driver. - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but the branch is merged here too to account for infrastructural changes). - The sx150x driver now supports the sx1502" * tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (220 commits) gpio: generic: make bgpio_pdata always visible gpiolib: fix chip order in gpio list gpio: mpc8xxx: Do not use gpiochip_get_data() in mpc8xxx_gpio_save_regs() gpio: mm-lantiq: Do not use gpiochip_get_data() in ltq_mm_save_regs() gpio: brcmstb: Allow building driver for BMIPS_GENERIC gpio: brcmstb: Set endian flags for big-endian MIPS gpio: moxart: fix build regression gpio: xilinx: Do not use gpiochip_get_data() in xgpio_save_regs() leds: pca9532: use gpiochip data pointer leds: tca6507: use gpiochip data pointer hid: cp2112: use gpiochip data pointer bcma: gpio: use gpiochip data pointer avr32: gpio: use gpiochip data pointer video: fbdev: via: use gpiochip data pointer gpio: pch: Optimize pch_gpio_get() Revert "pinctrl: lantiq: Implement gpio_chip.to_irq" pinctrl: nsp-gpio: use gpiochip data pointer pinctrl: vt8500-wmt: use gpiochip data pointer pinctrl: exynos5440: use gpiochip data pointer pinctrl: at91-pio4: use gpiochip data pointer ...

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "We've had quite busy weeks in this cycle. Looking at ALSA core, the significant changes are a few fixes wrt timer and sequencer ioctls that have been revealed by fuzzer recently. Other than that, ASoC core got a few updates about DAI link handling, but these are rather straightforward refactoring. In drivers scene, ASoC received quite lots of new drivers in addition to bunch of updates for still ongoing Intel Skylake support and topology API. HD-audio gained a new HDMI/DP hotplug notification via component. FireWire got a pile of code refactoring/updates with SCS.1x driver integration. More highlights are shown below. [ NOTE: this contains also many commits for DRM. This is due to the pull of drm stable branch into sound tree, as the base of i915 audio component work for HD-audio. The highlights below don't contain these DRM changes, as these are supposed to be pulled via drm tree in anyway sooner or later. ] Core: - Handful fixes to harden ALSA timer and sequencer ioctls against races reported by syzkaller fuzzer - Irq description string can be unique to each card; only for HD-audio for now ASoC: - Conversion of the array of DAI links to a list for supporting dynamically adding and removing DAI links - Topology API enhancements to make everything more component based and being able to specify PCM links via topology - Some more fixes for the topology code, though it is still not final and ready for enabling in production; we really need to get to the point where that can be done - A pile of changes for Intel SkyLake drivers which hopefully deliver some useful initial functionality for systems with this chipset, though there is more work still to come - Lots of new features and cleanups for the Renesas drivers - ANC support for WM5110 - New drivers: Imagination Technologies IPs, Atmel class D speaker, Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP - Rename PCM1792a driver to be generic pcm179x HD-Audio: - Use audio component for i915 HDMI/DP hotplug handling - On-demand binding with i915 driver - bdl_pos_adj parameter adjustment for Baytrail controllers - Enable power_save_node for CX20722; this shouldn't lead to regression, hopefully - Kabylake HDMI/DP codec support - Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell machines - A few code refactoring FireWire: - Lots of code cleanup and refactoring - Integrate the support of SCS.1x devices into snd-oxfw driver; snd-scs1x driver is obsoleted USB-audio: - Fix possible NULL dereference at disconnection - A regression fix for Native Instruments devices Misc: - A few code cleanups of fm801 driver" * tag 'sound-4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (722 commits) ALSA: timer: Code cleanup ALSA: timer: Harden slave timer list handling ALSA: hda - Add fixup for Dell Latitidue E6540 ALSA: timer: Fix race among timer ioctls ALSA: hda - add codec support for Kabylake display audio codec ALSA: timer: Fix double unlink of active_list ALSA: usb-audio: Fix mixer ctl regression of Native Instrument devices ALSA: hda - fix the headset mic detection problem for a Dell laptop ALSA: hda - Fix white noise on Dell Latitude E5550 ALSA: hda_intel: add card number to irq description ALSA: seq: Fix race at timer setup and close ALSA: seq: Fix missing NULL check at remove_events ioctl ALSA: usb-audio: Avoid calling usb_autopm_put_interface() at disconnect ASoC: hdac_hdmi: remove unused hdac_hdmi_query_pin_connlist ASoC: AMD: Add missing include file ALSA: hda - Fixup inverted internal mic for Lenovo E50-80 ALSA: usb: Add native DSD support for Oppo HA-1 ASoC: Make aux_dev more like a generic component ASoC: bcm2835: cleanup includes by ordering them alphabetically ASoC: AMD: Manage ACP 2.x SRAM banks power ...

2016-01-15ALSA: timer: Harden slave timer list handlingTakashi Iwai1-4/+14
A slave timer instance might be still accessible in a racy way while operating the master instance as it lacks of locking. Since the master operation is mostly protected with timer->lock, we should cope with it while changing the slave instance, too. Also, some linked lists (active_list and ack_list) of slave instances aren't unlinked immediately at stopping or closing, and this may lead to unexpected accesses. This patch tries to address these issues. It adds spin lock of timer->lock (either from master or slave, which is equivalent) in a few places. For avoiding a deadlock, we ensure that the global slave_active_lock is always locked at first before each timer lock. Also, ack and active_list of slave instances are properly unlinked at snd_timer_stop() and snd_timer_close(). Last but not least, remove the superfluous call of _snd_timer_stop() at removing slave links. This is a noop, and calling it may confuse readers wrt locking. Further cleanup will follow in a later patch. Actually we've got reports of use-after-free by syzkaller fuzzer, and this hopefully fixes these issues.

2016-01-14ALSA: timer: Fix race among timer ioctlsTakashi Iwai1-13/+19
ALSA timer ioctls have an open race and this may lead to a use-after-free of timer instance object. A simplistic fix is to make each ioctl exclusive. We have already tread_sem for controlling the tread, and extend this as a global mutex to be applied to each ioctl. The downside is, of course, the worse concurrency. But these ioctls aren't to be parallel accessible, in anyway, so it should be fine to serialize there.

2016-01-13ALSA: timer: Fix double unlink of active_listTakashi Iwai1-1/+1
ALSA timer instance object has a couple of linked lists and they are unlinked unconditionally at snd_timer_stop(). Meanwhile snd_timer_interrupt() unlinks it, but it calls list_del() which leaves the element list itself unchanged. This ends up with unlinking twice, and it was caught by syzkaller fuzzer. The fix is to use list_del_init() variant properly there, too.

2016-01-10ASoC: Make aux_dev more like a generic componentMengdong Lin1-69/+77
aux_dev is mainly used by the machine driver to specify analog devices, which are registered as codecs. Making it more like a generic component can help the machine driver to use it to specify any component with topology info by name. Details: - Remove the stub 'rtd_aux' array from the soc card. - Add a list 'aux_comp_list' to store the components of aux_devs. And add a list head 'list_aux' to struct snd_soc_component, for adding such components to the above list. - Add a 'init' ops to a component for machine specific init. soc_bind_aux_dev() will set it to be aux_dev's init. And it will be called when probing the component. - soc_bind_aux_dev() will also search components by name of an aux_dev, since it may not be a codec. - Move probing of aux_devs before checking new DAI links brought by topology. - Move removal of aux_devs later than removal of links. Because topology of aux components may register DAIs and the DAI drivers will go with removal of the aux components, we want soc_remove_link_dais() to remove the DAIs at first.
