Subject: [PATCH 12/13] mtd: spi-nor: Void return type for spi_nor_clear_sr/fsr()
Date: Wed, 11 Sep 2019 09:41:24 +0000
Message-ID: <20190911094031.17615-13-tudor.ambarus@microchip.com> (raw)
In-Reply-To: <20190911094031.17615-1-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.
