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.
