Linux Kernel 4.11 was released yesterday, and 9 different Collabora developers contributed a total of 44 patches, an increase of 5 patches from version 4.10. The majority of Collabora's work this time was around fixes and clean ups in the DRM. In addition to our contributions as authors, Collabora also added 22 Reviewed-by tags for patches reviewed by our engineers. You can learn more information about the v4.11 merge window in LWN.net's extensive coverage: part 1, part 2 and part 3.

Now here is a look at the specific changes made by Collaborans. To begin with, Enric Balletbo fixed an issue and improved documentation of IIO regarding sensors and also added support for several buses and peripherals for the Toby-Churchill SL50 board. Romain Perier added an ASoC machine driver for Rockchip rk3288-based boards that have an HDMI and analog audio output, and also added support for slave mode in the Everest Semi ES8328 audio codec, while including ES8388 as a compatible device in the ES8328's codec driver.

For his part, Tomeu Vizoso fixed the sink display error in DRM EDID when no deep color is available for Rotel RSX-1058 and also fixed several issues and code cleanups regarding CRC in DRM and integrated the new CRC debugfs API in i915. Gabriel Krisman Bertazi, who wrote a great article recently on tracing the user space and Operating System interactions, made several improvements to DRM by adding documentation, cleaning up the code and fixing several issues, including allowing QXL build when FBDEV_EMULATION is disabled.

Lastly, Daniel Stone, Collabora's Graphics Lead, fixed an important issue in DRM regarding the use of Atomic State in legacy ioctls, while Fabien Lahoudere cleaned up the code for the Epson RTC removing an unnecessary spinlock, and Robert Foss fixed a copy of uninitialized memory in Ethernet qed code.
