Subject: [PATCH v2 04/13] iio: gyro: bmg160_i2c: Use vsprintf extension %pe for symbolic error name
Date:   Sun, 22 Mar 2020 22:53:06 +0530
Message-Id: <5b9a92dee27f406556b4c945f773ef9b5eea825c.1584897364.git.nish.malpani25@gmail.com>

Precedence: bulk

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.

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].
