2013-01-02leds: leds-gpio: set devm_gpio_request_one() flags param correctlyJavier Martinez Canillas1-2/+3
commit a99d76f leds: leds-gpio: use gpio_request_one changed the leds-gpio driver to use gpio_request_one() instead of gpio_request() + gpio_direction_output() Unfortunately, it also made a semantic change that breaks the leds-gpio driver. The gpio_request_one() flags parameter was set to: GPIOF_DIR_OUT | (led_dat->active_low ^ state) Since GPIOF_DIR_OUT is 0, the final flags value will just be the XOR'ed value of led_dat->active_low and state. This value were used to distinguish between HIGH/LOW output initial level and call gpio_direction_output() accordingly. With this new semantic gpio_request_one() will take the flags value of 1 as a configuration of input direction (GPIOF_DIR_IN) and will call gpio_direction_input() instead of gpio_direction_output(). int gpio_request_one(unsigned gpio, unsigned long flags, const char *label) { .. if (flags & GPIOF_DIR_IN) err = gpio_direction_input(gpio); else err = gpio_direction_output(gpio, (flags & GPIOF_INIT_HIGH) ? 1 : 0); .. } The right semantic is to evaluate led_dat->active_low ^ state and set the output initial level explicitly.

2012-12-26net/vxlan: Use the underlying device index when joining/leaving multicast groupsYan Burman1-2/+4
The socket calls from vxlan to join/leave multicast group aren't using the index of the underlying device, as a result the stack uses the first interface that is up. This results in vxlan being non functional over a device which isn't the 1st to be up. Fix this by providing the iflink field to the vxlan instance to the multicast calls.

2012-12-26PCI/PM: Do not suspend port if any subordinate device needs PME pollingHuang Ying1-1/+19
Ulrich reported that his USB3 cardreader does not work reliably when connected to the USB3 port. It turns out that USB3 controller failed to awaken when plugging in the USB3 cardreader. Further experiments found that the USB3 host controller can only be awakened via polling, not via PME interrupt. But if the PCIe port to which the USB3 host controller is connected is suspended, we cannot poll the controller because its config space is not accessible when the PCIe port is in a low power state. To solve the issue, the PCIe port will not be suspended if any subordinate device needs PME polling.

Reverting that commit entirely fixes the problem for me. However, commit f0ed2ce840b3 appears to do more than it follows from its changelog, because the changelog only says about the changes related to ctrls->error_idx, while the commit additionally changes error codes returned by various functions in uvc_ctrl.c and uvc_v4l2.c. It turns out that the changes of the returned error codes confuse the user spce, so it is sufficient to revert the part of commit f0ed2ce840b3 not mentioned in its changelog to fix the problem.

2012-12-21hwmon: (lm73} Detect and report i2c bus errorsChris Verges1-5/+11
If an LM73 device does not exist on an I2C bus, attempts to communicate with the device result in an error code returned from the i2c read/write functions. The current lm73 driver casts that return value from a s32 type to a s16 type, then converts it to a temperature in celsius. Because negative temperatures are valid, it is difficult to distinguish between an error code printed to the response buffer and a negative temperature recorded by the sensor. The solution is to evaluate the return value from the i2c functions before performing any temperature calculations. If the i2c function did not succeed, the error code should be passed back through the virtual file system layer instead of being printed into the response buffer.

Of particular note: - Disable broken WRITE SAME support in all targets except linear and striped. Use it when kcopyd is zeroing blocks. - Remove several mempools from targets by moving the data into the bio's new front_pad area(which dm calls 'per_bio_data'). - Fix a race in thin provisioning if discards are misused. - Prevent userspace from interfering with the ioctl parameters and use kmalloc for the data buffer if it's small instead of vmalloc. - Throttle some annoying error messages when I/O fails." * tag 'dm-3.8-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm: (36 commits) dm stripe: add WRITE SAME support dm: remove map_info dm snapshot: do not use map_context dm thin: dont use map_context dm raid1: dont use map_context dm flakey: dont use map_context dm raid1: rename read_record to bio_record dm: move target request nr to dm_target_io dm snapshot: use per_bio_data dm verity: use per_bio_data dm raid1: use per_bio_data dm: introduce per_bio_data dm kcopyd: add WRITE SAME support to dm_kcopyd_zero dm linear: add WRITE SAME support dm: add WRITE SAME support dm: prepare to support WRITE SAME dm ioctl: use kmalloc if possible dm ioctl: remove PF_MEMALLOC dm persistent data: improve improve space map block alloc failure message dm thin: use DMERR_LIMIT for errors ...

2012-12-21tuntap: dont use a private kmem_cacheEric Dumazet1-21/+3
Commit 96442e42429 (tuntap: choose the txq based on rxq) added a per tun_struct kmem_cache. As soon as several tun_struct are used, we get an error because two caches cannot have same name. Use the default kmalloc()/kfree_rcu(), as it reduce code size and doesn't have performance impact here.
