Mauro Carvalho Chehab befd6e645c V4L/DVB (10511): saa7134: get rid of KBL 
KBL is not needed on saa7134, so, let's remove it.

However, we should take some care to avoid opening the module while
initializing it. This issue exists with newer udev's that opens a device
as soon as the driver is registered. So, a proper lock is needed on
open.
