Subject: [PATCH] drivers/md.c: Make bio_alloc_mddev return bio_alloc_bioset
Date:   Sat, 22 Dec 2018 08:08:45 -0200
Message-Id: <20181222100845.566772-1-marcos.souza.org@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

bio_alloc_bioset return a bio pointer or NULL, so we can avoid storing
the returned data into a new variable.
