Subject: [PATCH v15 01/15] mtd: spi-nor: core: use EOPNOTSUPP instead of ENOTSUPP
Date: Fri, 2 Oct 2020 01:50:31 +0530
Message-ID: <20201001202045.21499-2-p.yadav@ti.com> (raw)
In-Reply-To: <20201001202045.21499-1-p.yadav@ti.com>

ENOTSUPP is not a SUSV4 error code. Using EOPNOTSUPP is preferred
in its stead.
