Subject: [PATCH 7/8] mtd_blkdevs: simplify blktrans_getgeo
Date: Mon, 23 Aug 2021 09:33:58 +0200 [thread overview]
Message-ID: <20210823073359.705281-8-hch@lst.de> (raw)
In-Reply-To: <20210823073359.705281-1-hch@lst.de>
No need to grab a mtd_blktrans_dev given that ->open already holds one
and ->getgeo can only be called on an open disk.
