From 9465d5324834f1e99c1343b7bbdc5e6ac8c83f87 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Wed, 31 Oct 2007 19:27:57 +0800 Subject: [PATCH] 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.
