From c3f139b65585a5f29df47b2302ff8dbd9bdad0b0 Mon Sep 17 00:00:00 2001 From: Jassi Brar Date: Fri, 3 Sep 2010 10:36:46 +0900 Subject: [PATCH] spi/s3c64xx: Fix incorrect reuse of 'val' local variable. Instead of, wrongly, reusing the 'val' variable, use a dedicated one for reading the status register.
