Subject: mtd: spi-nor-core: Don't check for zero length in spi_nor_write() / spi_nor_erase()
X-Git-Tag: v2025.01-rc5-pxa1908~1669^2~8
X-Git-Url: http://git.dujemihanovic.xyz/%7B%7B%20.Permalink%20%7D%7D?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.
