V4L/DVB (7469): Preparation for supporting new devices, cleanup and saneness
To prepare the support for new device to the flexcop-family some preparation and cleanups was done + some saneness: - created an i2c-adapter for each i2c-port available. Easier usage for devices with several device on different i2c-busses - initialize i2c before doing the eeprom read - changed the way to attach the different frontends, easier to read now - enabled support for i2c-devices having no register address (1-byte access) Signed-off-by: Patrick Boettcher <pb@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
