[PATCH] iio: dpot-dac: fix code comment in dpot_dac_read_raw()
From: Gustavo A. R. Silva
Date: Tue Aug 25 2020 - 20:02:54 EST
After the replacement of the /* fall through */ comment with the
fallthrough pseudo-keyword macro, the natural reading of a code
comment was broken.
Fix the natural reading of such a comment and make it intelligible.
