media: vidtv: do some cleanups at the driver
Do some cleanups at the coding style of the driver: - remove "inline" declarations; - use reverse xmas-tree for local var declarations; - Adjust some indent to avoid breaking 80-cols; - Cleanup some comments. No functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
