Subject: [PATCH 37/39] ide: remove ide_driver_proc_write
Date: Thu, 19 Apr 2018 14:41:38 +0200 [thread overview]
Message-ID: <20180419124140.9309-38-hch@lst.de> (raw)
In-Reply-To: <20180419124140.9309-1-hch@lst.de>
The driver proc file hasn't been writeable for a long time, so this is
just dead code.
