Subject: ata/sata_fsl: Remove unnecessary SCR cases
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9465d5324834f1e99c1343b7bbdc5e6ac8c83f87;p=openwrt%2Fstaging%2Fblogic.git

ata/sata_fsl: Remove unnecessary SCR cases

SCRs in the driver map to the standard values found in include/linux/ata.h,
so no need for individual scr_read/scr_write case statements duplicating
the natural value.
