From: Marek Behún Date: Tue, 5 Oct 2021 13:56:02 +0000 (+0200) Subject: mtd: spi-nor-core: Don't check for zero length in spi_nor_write() / spi_nor_erase() X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7398c1b758e70708edc1d0aced2e2b07ded1ed7e;p=u-boot.git mtd: spi-nor-core: Don't check for zero length in spi_nor_write() / spi_nor_erase() This check is already done in all callers: mtdcore's mtd_write() / mtd_erase(), legacy spi_nor_write() / spi_flash_erase(). No reason to do this here as well.
