4166b47c2b iio:light: drop assign iio_info.driver_module and iio_trigger_ops.owner
The equivalent of both of these are now done via macro magic when
the relevant register calls are made.  The actual structure
elements will shortly go away.

0ff8c78df8 iio:light:cm3323: replace unneeded variable
In cm3323_read_raw() i is used as return variable for the integration time
index. The also existing return variable ret however is unused in this
case, although appropriate. Replace i with ret and drop it.
