Subject: iio: addac: ad74413: fix resistance input processing
From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
commit 24febc99ca725dcf42d57168a2f4e8a75a5ade92 upstream.
On success, ad74413r_get_single_adc_result() returns IIO_VAL_INT aka
1. So currently, the IIO_CHAN_INFO_PROCESSED case is effectively
equivalent to the IIO_CHAN_INFO_RAW case, and we never call
ad74413r_adc_to_resistance_result() to convert the adc measurement to
ohms.
Check ret for being negative rather than non-zero.
