Subject: [PATCH 43/45] f2fs: remove a few bd_part checks
Date: Tue, 24 Nov 2020 14:27:49 +0100	[thread overview]
Message-ID: <20201124132751.3747337-44-hch@lst.de> (raw)
In-Reply-To: <20201124132751.3747337-1-hch@lst.de>

bd_part is never NULL for a block device in use by a file system, so
remove the checks.
