[media] Staging: tm6000: fix braces, tabs, comments and space coding style issue in tm6000-video.c
This is a patch to the tm6000-video.c file that fixed up a braces, tabs, comments and space Errors and Warnings found by the checkpatch.pl tools. [mchehab@redhat.com: some changes didn't apply as it were based to an older version, so used patch -f to apply only the changes that are OK] Signed-off-by: Ruslan Pisarev <ruslan@rpisarev.org.ua> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
