UPSTREAM: iio: adc: at91-sama5d2_adc: fix an error code in at91_adc_allocate_trigger()

Browse Source 
commit 73a428b37b9b538f8f8fe61caa45e7f243bab87c upstream.

The at91_adc_allocate_trigger() function is supposed to return error
pointers.  Returning a NULL will cause an Oops.

Fixes: 5e1a1da0f8 ("iio: adc: at91-sama5d2_adc: add hw trigger and buffer support")
