Subject: [PATCH] regulator: ab3100: Remove ab3100_regulators_remove function
Date: Thu, 7 Mar 2019 21:53:56 +0800 [thread overview]
Message-ID: <20190307135356.15736-1-axel.lin@ingics.com> (raw)
Current code is using devm_regulator_register() so it is not necessary
to save reg->rdev for clean up. Remove *rdev from struct ab3100_regulator,
then ab3100_regulators_remove() can be removed as well.
