Subject: [PATCH v2 29/45] mfd: acer-a500: Use devm_register_power_handler()
Date: Thu, 28 Oct 2021 00:16:59 +0300 [thread overview]
Message-ID: <20211027211715.12671-30-digetx@gmail.com> (raw)
In-Reply-To: <20211027211715.12671-1-digetx@gmail.com>
Use devm_register_power_handler() that replaces global pm_power_off
variable and allows to register multiple power-off handlers. It also
provides restart-handler support, i.e. all in one API.
