V4L/DVB (8103): videodev: fix/improve ioctl debugging
Various ioctl debugging fixes and improvements: - use %x rather than %d for control IDs and bitmask fields - make two arrays const - show the whole control array for the ext_ctrl ioctls - print pix_fmt for V4L2_BUF_TYPE_VIDEO_OUTPUT - show full type name rather than an integer - fix CROPCAP debugging - fix G/S_TUNER debugging - show error code in case of an error - other small cleanups Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
