V4L/DVB (3697): More msp3400 and bttv fixes
- remove obsolete VIDIOC_S_INPUT i2c call in bttv - translate VIDIOCSFREQ to VIDIOC_S_FREQUENCY in i2c call - improve muting during carrier scan in msp3400 - don't start scan unless really needed. - no longer reset chip for msp3400c/d. - remove v4l2 check in tuner-core (radio stops after using the TV) - add missing VIDIOC_INT_ strings in v4l2-common.c Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
