If so, Sedji, you > don't need to write yet another driver for it. stk-sensor.c isn't a proper i2c driver: it's programmed through registers on the stk1125 control interface. That driver should probably be rewritten as a stk1125 driver that creates an i2c adapter which would allow stk-sensor.c to be rewritten as a proper i2c subdev. Anyway, stk-sensor.c won't be (nor needs to be) converted. This obviously means that stk-sensor is not reusable in any other driver. There is no easy solution to that, other than a stk-*.c rewrite. Note that there is also ov965x support in gspca/ov534.c. I think that several gspca drivers should really be rewritten so that they just create an i2c adapter and load the i2c sensor subdev.
