From daea65a7be76953bb80d13d0ac43e7441fd42cdf Mon Sep 17 00:00:00 2001 From: Daniel Thompson Date: Tue, 23 Sep 2014 08:31:30 +0100 Subject: [PATCH] serial: asc: Conditionally use readl_relaxed (COMPILE_TEST) Commit 08177ece596c ("serial: asc: Adopt readl_/writel_relaxed()) is regressing the m68k allmodconfig build. This is due to the unconditional use of readl_relaxed() which, although documented, does not currently exist for m68k. This is trivially fixable for st-asc because we can just update the asc_in() accessor to make this conditional.
