V4L/DVB (5765): SN9C1xx driver updates
- Add support for pair OV7630+SN9C120 - Better and safe locking mechanism of the device structure on open(), close() and disconnect() - Use kref for handling device deallocation - Generic cleanups Signed-off-by: Luca Risolia <luca.risolia@studio.unibo.it> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
