Subject: [PATCH 13/23] mtd: spi-nor: Void return type for spi_nor_clear_sr/fsr()
Date: Tue, 17 Sep 2019 15:55:22 +0000 [thread overview]
Message-ID: <20190917155426.7432-14-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20190917155426.7432-1-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.
