Subject: mmc: mmc_spi: Select CRC16 if CRC checking is enabled
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3f208e1a99203c8ff257202a2e8447cc43a666c9;p=thirdparty%2Fu-boot.git

mmc: mmc_spi: Select CRC16 if CRC checking is enabled

Currently CRC16 is not selected when CRC checking is enabled and
if it wasn't enabled in the config otherwise the build will fail
because of references to crc16_ccitt() that doesn't exist.
