Third round of iio fixes for the 3.16 cycle.
* Lots of hid sensors component drivers had a bug due to a local variable
whose name suggested it was returned from the read_raw function not
infact being returned (ret vs ret_type). Fixed and unused ret removed.
* Block a possible race condition in tcs3472 by locking around some
dependant i2c messages.
* Fix bug in the am335x driver fifo setup that occurs if the final
channel enabled takes certain values.
