Subject: [PATCH AUTOSEL 4.14 02/10] power: supply: bq27xxx: Use mod_delayed_work() instead of cancel() + schedule()

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit 59dddea9879713423c7b2ade43c423bb71e0d216 ]

Use mod_delayed_work() instead of separate cancel_delayed_work_sync() +
schedule_delayed_work() calls.
