Subject: [PATCH v2 12/13] iio: light: st_uvis25_spi: Use vsprintf extension %pe for symbolic error name
Date: Sun, 22 Mar 2020 22:53:14 +0530	[thread overview]
Message-ID: <45d5a4bf468c490522d55f5c763061976804bf67.1584897364.git.nish.malpani25@gmail.com> (raw)
In-Reply-To: <cover.1584897364.git.nish.malpani25@gmail.com>

Utilize %pe format specifier from vsprintf while printing error logs
with dev_err(). Discards the use of unnecessary explicit casting and
prints symbolic error name which might prove to be convenient during
debugging.

Signed-off-by: Nishant Malpani <nish.malpani25@gmail.com>

Changes in v2:
  - Rewrite commit subject line outlining the usage of %pe.
  - Add a separator between regmap and its error name.

Based on conversations in [1] & [2].
