Subject: [PATCH] iio: dpot-dac: fix code comment in dpot_dac_read_raw()
Date: Tue, 25 Aug 2020 19:08:44 -0500	[thread overview]
Message-ID: <20200826000844.GA16807@embeddedor> (raw)

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.
