Subject: [RFC PATCH 7/7] watchdog: retu_wdt: Clean-up by using managed work init
Date: Sat, 13 Feb 2021 14:18:48 +0200 [thread overview]
Message-ID: <f157b14a3bd03cb94c9d11e3a6fc995bf4245edf.1613216412.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1613216412.git.matti.vaittinen@fi.rohmeurope.com>
Few drivers implement remove call-back only for ensuring a delayed
work gets cancelled prior driver removal. Clean-up these by switching
to use devm_delayed_work_autocancel() instead.
This change is compile-tested only. All testing is appreciated.
