Subject: [PATCH] mtd: spi-nor: Introduce templates for SPI NOR operations
Date: Fri, 4 Mar 2022 11:30:11 +0200 [thread overview]
Message-ID: <20220304093011.198173-1-tudor.ambarus@microchip.com> (raw)
Clean the op declaration and hide the details of each op. With this it
results a cleanner, easier to read code. No functional change expected.
