2014-06-25leds: add led-class attribute-group supportJohan Hovold1-2/+3
Allow led-class devices to be created with optional attribute groups. This is needed in order to allow led drivers to create custom device attributes in a race-free manner. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Bryan Wu <cooloney@gmail.com>

git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c new drivers from Wolfram Sang: "Here is a pull request from i2c hoping for the "new driver" rule. Originally, I wanted to send this request during the merge window, but code checkers with very recent additions complained, so a few fixups were needed. So, some more time went by and I merged rc1 to get a stable base" So the "new driver" rule is really about drivers that people absolutely need for the kernel to work on new hardware, which is not so much the case for i2c. So I considered not pulling this, but eventually relented. Just for FYI: the whole (and only) point of "new drivers" is not that new drivers cannot regress things (they can, and they have - by triggering badly tested code on machines that never triggered that code before), but because they can bring to life machines that otherwise wouldn't be useful at all without the drivers. So the new driver rule is for essential things that actual consumers would care about, ie devices like networking or disk drivers that matter to normal people (not server people - they run old kernels anyway, so mainlining new drivers is irrelevant for them). * 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux: i2c: sun6-p2wi: fix call to snprintf i2c: rk3x: add NULL entry to the end of_device_id array i2c: sun6i-p2wi: use proper return value in probe i2c: sunxi: add P2WI (Push/Pull 2 Wire Interface) controller support i2c: sunxi: add P2WI DT bindings documentation i2c: rk3x: add driver for Rockchip RK3xxx SoC I2C adapter

2014-06-19tty/serial: fix 8250 early console option passing to regular consoleRob Herring2-2/+5
In the conversion to generic early console, the passing of options from the early 8250 console to the regular ttyS console was broken. This resulted in the baud rate changing when switching consoles during boot. This feature allows specifying a single console option on the kernel command line rather than both an early console and regular serial tty console. It would be nice to generalize this feature. However, it only works if the correct baud rate can be probed early which is not the case on many platforms which have non-standard UART clock rates. So for now, this is left as an 8250 specific feature.

2014-06-19tty: Correct INPCK handlingPeter Hurley1-9/+10
If INPCK is not set, input parity detection should be disabled. This means parity errors should not be received from the tty driver, and the data received should be treated normally. SUS v3, 11.2.2, General Terminal Interface - Input Modes, states: "If INPCK is set, input parity checking shall be enabled. If INPCK is not set, input parity checking shall be disabled, allowing output parity generation without input parity errors. Note that whether input parity checking is enabled or disabled is independent of whether parity detection is enabled or disabled (see Control Modes). If parity detection is enabled but input parity checking is disabled, the hardware to which the terminal is connected shall recognize the parity bit, but the terminal special file shall not check whether or not this bit is correctly set." Ignore parity errors reported by the tty driver when INPCK is not set, and handle the received data normally.

2014-06-19serial: Fix IGNBRK handlingPeter Hurley34-32/+44
If IGNBRK is set without either BRKINT or PARMRK set, some uart drivers send a 0x00 byte for BREAK without the TTYBREAK flag to the line discipline, when it should send either nothing or the TTYBREAK flag set. This happens because the read_status_mask masks out the BI condition, which uart_insert_char() then interprets as a normal 0x00 byte. SUS v3 is clear regarding the meaning of IGNBRK; Section 11.2.2, General Terminal Interface - Input Modes, states: "If IGNBRK is set, a break condition detected on input shall be ignored; that is, not put on the input queue and therefore not read by any process." Fix read_status_mask to include the BI bit if IGNBRK is set; the lsr status retains the BI bit if a BREAK is recv'd, which is subsequently ignored in uart_insert_char() when masked with the ignore_status_mask.

With commit aed3f9d498b ("staging: comedi: addi_apci_1564: absorb apci1564_reset()"), the apci 1564 driver has gained a dependency on the addi watchdog module, which is not reflected correctly in Kconfig, and that can lead to link errors when the watchdog is disabled. This adds an explicit 'select', like it is done in the other addi apci drivers that need it.

2014-06-18cpufreq: unlock when failing cpufreq_update_policy()Aaron Plattner1-6/+4
Commit bd0fa9bb455d introduced a failure path to cpufreq_update_policy() if cpufreq_driver->get(cpu) returns NULL. However, it jumps to the 'no_policy' label, which exits without unlocking any of the locks the function acquired earlier. This causes later calls into cpufreq to hang. Fix this by creating a new 'unlock' label and jumping to that instead.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus Jonathan writes: First set of IIO fixes for the 3.16 cycle. A mixed bag of fixes, many of which feel just to late for 3.15. * hid sensors - some devices need a feature report request in order to change power state. This isn't part of the spec, but has been observed on several devices and does no harm to others. * mpl3115 has had two errors in the buffer description fixed. The presure is signed, not unsigned and the temperature has 12 bits rather than 16. These could lead to incorrect interpretation of the data in userspace. * tsl2x7x - the high byte of the proximity thresholds should be written along with the low byte (which was). This could lead to interesting results with large thresholds. * twl4030 - a flag to specify processed values were required was not set when initializing a reading. As such values returned were in an unknown state. Fixed by simply initializing it appropriately. * IIO_SIMPLE_DUMMY_BUFFER did not select IIO_BUFFER leading to randconfig build errors. * ak8975 was applying an unwanted le16_to_cpu conversion as the i2c framework already performs one. As such for big endian systems, the bytes would be in the wrong order in the magnetic field measurements reported. * mxs-lradc - the controllable voltage dividers were not enabled / disabled for later channels than the first one during conversion. * at91_adc error handling returned -ENOMEM in a u8. Return value of at91_adc_get_trigger_value_by_name changed to int thus allowing -ENOMEM and also original values to be returned. * mcb - mcb_request_mem returns and ERR_PTR but the caller was checking for NULL to detect an error.

2014-06-17usb: fix hub-port pm_runtime_enable() vs runtime pm transitionsDan Williams3-19/+54
Commit 9262c19d14c4 "usb: disable port power control if not supported in wHubCharacteristics" gated enabling runtime pm for usb_port devices on whether the parent hub supports power control, which causes a regression. The port must still be allowed to carry out runtime pm callbacks and receive a -EAGAIN or -EBUSY result. Otherwise the usb_port device will transition to the pm error state and trigger the same for the child usb_device. Prior to the offending commit usb_hub_create_port_device() arranged for runtime pm to be disabled is dev_pm_qos_expose_flags() failed. Instead, force the default state of PM_QOS_FLAG_NO_POWER_OFF flag to be set prior to enabling runtime pm. If that policy can not be set then fail registration.
