Subject: [PATCH v3 11/32] mtd: spi-nor: Drop redundant error reports in Reg Ops callers
Date: Tue, 29 Oct 2019 11:17:05 +0000	[thread overview]
Message-ID: <20191029111615.3706-12-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20191029111615.3706-1-tudor.ambarus@microchip.com>

From: Tudor Ambarus <tudor.ambarus@microchip.com>

Drop the error messages from the callers, since the callees
already print an error message in case of failure.
