V4L/DVB (5474): SN9C1xx driver updates
@ Don't assume that SOF headers can't cross packets boundaries @ Fix compression quality selection + Add support for MI-0360 image sensor * Documentation updates @ Fix sysfs @ MI0343 rewritten * HV7131R color fixes and add new ABLC control * Rename the archive from "sn9c102" to "sn9c1xx" * fix typos * better support for TAS5110D @ fix OV7630 wrong colors @ Don't return an error if no input buffers are enqueued yet on VIDIOC_STREAMON * Add informations about colorspaces * More appropriate error codes in case of failure of some system calls * More precise hardware detection * Add more informations about supported hardware in the documentation + More supported devices + Add support for HV7131R image sensor Signed-off-by: Luca Risolia <email@example.com> Signed-off-by: Mauro Carvalho Chehab <firstname.lastname@example.org>
