V4L/DVB (12701): saa7134: ir-kbd-i2c init data needs a persistent object
ir-kbd-i2c's ir_probe() function can be called much later (i.e. at
ir-kbd-i2c module load), than the lifetime of a struct IR_i2c_init_data
allocated off of the stack in cx18_i2c_new_ir() at registration time.
Make sure we pass a pointer to a persistent IR_i2c_init_data object at
i2c registration time.
Thanks to Brian Rogers, Dustin Mitchell, Andy Walls and Jean Delvare to
rise this question.
Before this patch, if ir-kbd-i2c were probed after SAA7134, trash data
were used.
Compile tested only, but the patch is identical to em28xx one. So, it
should work properly.
