[media] gspca - pac7302: Cleanup source
- copyright change - use the kbuild module name for messages - change module author - remove '__' from the variable types - use u8 instead of 'unsigned char' - simplify the error messages - remove useless initialization - remove useless traces Signed-off-by: Jean-François Moine <moinejf@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
