Subject: iio/axp288_adc: add missing channel info mask
From: Jacob Pan <[email protected]>
commit d0716b0ea4ce11a13477163c14b26e180922ba51 upstream.
Commit 65de7654d39c70c2b ("iio: iio: Fix iio_channel_read return if
channel havn't info") added a check for valid info masks.
This patch adds missing channel info masks for all ADC channels.
Otherwise, iio_read_channel_raw() would return -EINVAL when called
by consumer drivers.
Note that the change of _processed to _raw actually fixes an ABI abuse
in the original driver where it was used to avoid some special handling
rather than because it was correct.
