Subject: [PATCH 07/12] driver: base: cpu: export device_online/offline
Date: Wed, 30 Oct 2019 15:38:32 +0000 [thread overview]
Message-ID: <20191030153837.18107-8-qais.yousef@arm.com> (raw)
In-Reply-To: <20191030153837.18107-1-qais.yousef@arm.com>
And the {lock,unlock}_device_hotplug so that they can be used from
modules.
This is in preparation to replace cpu_up/down with
device_online/offline; which kernel/torture.c will require to be
exported to be built as a module.
