V4L/DVB (10761): cx18: Change log lines for internal subdevs and fix tveeprom reads
Give messages originating from internal subdevs a header using the subdev's name. Fixed an uninitialized variable problem with reading the EEPROM, noticed from log output. Got rid of the unused cx18_av_exit() function. Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
