From 72c60683282a6cd047db47d605eb96e2a6fac72c Mon Sep 17 00:00:00 2001 From: Mike McCormack Date: Tue, 1 Sep 2009 03:54:27 +0000 Subject: [PATCH] sky2: Use 32bit read to read Y2_VAUX_AVAIL B0_CTST is a 24bit register according to the vendor driver (sk98lin). A 16bit read on B0_CTST will always return 0 for Y2_VAUX_AVAIL (1<<16), so use a 32bit read when testing Y2_VAUX_AVAIL Signed-off-by: Mike McCormack Acked-by: Stephen Hemminger Signed-off-by: David S.
