2018-04-04media: cx231xx: Increase USB bridge bandwidthBrad Love
The cx231xx USB bridge has issue streaming QAM256 DVB-C channels. QAM64 channels were fine, but QAM256 channels produced corrupted transport streams. cx231xx alt mode 4 does not provide enough bandwidth to acommodate QAM256 DVB-C channels, most likely DVB-T2 channels would break up as well. Alt mode 5 increases bridge bandwidth to 90Mbps, and fixes QAM256 DVB-C streaming. Signed-off-by: Brad Love <brad@nextdimension.cc> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2018-03-23media: uvc: to the right check at uvc_ioctl_enum_framesizes()Mauro Carvalho Chehab
While the logic there is correct, it tricks both humans and machines, a the check if "i" var is not zero is actually to validate if the "frames" var was initialized when the loop ran for the first time. That produces the following warning: drivers/media/usb/uvc/uvc_v4l2.c:1192 uvc_ioctl_enum_framesizes() error: potentially dereferencing uninitialized 'frame'.

2018-03-21media: add tuner standby op, use where neededHans Verkuil
The v4l2_subdev core s_power op was used for two different things: power on/off sensors or video decoders/encoders and to put a tuner in standby (and only the tuner!). There is no 'tuner wakeup' op, that's done automatically when the tuner is accessed. The danger with calling (s_power, 0) to put a tuner into standby is that it is usually broadcast for all subdevs. So a video receiver subdev that supports s_power will also be powered off, and since there is no corresponding (s_power, 1) they will never be powered on again. In addition, this is specifically meant for tuners only since they draw the most current. This patch adds a new tuner op called 'standby' and replaces all calls to (core, s_power, 0) by (tuner, standby). This prevents confusion between the two uses of s_power. Note that there is no overlap: bridge drivers either just want to put the tuner into standby, or they deal with powering on/off sensors. Never both. This also makes it easier to replace s_power for the remaining bridge drivers with some PM code later. Whether we want something cleaner for tuners in the future is a separate topic. There is a lot of legacy code surrounding tuners, and I am very hesitant about making changes there.
