From mboxrd@z Thu Jan 1 00:00:00 1970 From: Masami Hiramatsu Date: Wed, 19 May 2021 14:46:34 +0900 Subject: [PATCH v4 12/14] dfu_mtd: Ignore non-implemented lock device failure In-Reply-To: <162140306116.47256.6799058439792039400.stgit@localhost> References: <162140306116.47256.6799058439792039400.stgit@localhost> Message-ID: <162140319389.47256.629728945246178860.stgit@localhost> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Ignore the non-implemented lock device failure on writing mtd via DFU. Without this fix, DFU write shows an error on such device even if it succeeded, because dfu->write_medium returns -EOPNOTSUPP.
