Subject: [PATCH v2 13/22] mtd: spi-nor: Void return type for spi_nor_clear_sr/fsr()
Date: Tue, 24 Sep 2019 07:46:34 +0000 [thread overview]
Message-ID: <20190924074533.6618-14-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20190924074533.6618-1-tudor.ambarus@microchip.com>
From: Tudor Ambarus <tudor.ambarus@microchip•com>
spi_nor_clear_sr() and spi_nor_clear_fsr() are called just in case
of errors. The callers didn't check their return value. Make them
of type void and print an error in case the operations fail.
