[PATCH 03/13] staging: iio: tsl2x7x: don't return error in IRQ handler

[Brian Masney]

tsl2x7x_event_handler() could return an error and this could cause the
interrupt to remain masked. We shouldn't return an error in the
interrupt handler so this patch always returns IRQ_HANDLED. An error
will be logged if one occurs.
