Subject: [PATCH 1/5] genhd: drop 'bool' argument from __device_add_disk()
Date: Wed, 25 Jul 2018 08:28:36 +0200	[thread overview]
Message-ID: <20180725062840.94114-2-hare@suse.de> (raw)
In-Reply-To: <20180725062840.94114-1-hare@suse.de>

Split off the last part of __device_add_disk() into __device_get_disk().
With that we can drop the 'bool' argument and streamline the function.
