[PATCH] v4l: 784: several improvement on i2c ir handling for em2820
- Several Improvement on I2C IR handling for em2820:
- moved Pinnacle IR table (ir_codes_em2820) to em2820-input.c
- IR struct renamed and moved to a header file.
- New file to handle em2820-specific IR.
- Some cleanups.
- attach now detects I2C IR and calls em2820-specific IR code
- IR compat code moved to compat.h
- New header with struct IR_i2c there, to allow it to be
used by board-specific input handlers.
- Some improvements at em28xx board detection:
- Board detection message improved to show interface and class.
- Now it doesn't touch audio interfaces.
