The first round of IIO fixes for the 3.11 cycle.

This set is larger than I would like, partly due to my lack of review
time in the weeks before the merge window and partly because a
couple of large drivers and the subsystem as a whole seem to be
getting a lot more exposure and testing recently.

1) A long term bug in trigger handling gave a double free of the device.

2) Wrong return value handling means offsets are ignored in
   iio_convert_raw_to_processed_unlocked.

3) The iio_channel_has_info utility function was incorrectly updated
   during the recent info_mask split, this is now fixed.

4) mxs-lradc has a couple of little fixes.

5) A couple of missing .driver_module entries meant that drivers
   could be removed from underneath their users.

6) Error path fixes for ad7303 and lis3l02dq.

7) The scale value for presure in the lps331ap driver was out by
   a factor of 100.
