From a6d710fefd1b2c209353a452d0f4c831b3af0da0 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 22 Mar 2011 13:09:50 +0100 Subject: ARM: pxafb: Fix access to nonexistent member of pxafb_info In case CONFIG_FB_PXA_OVERLAY is not defined, the pxafb_freq_transition() function tests nonexistent member of pxafb_info (since the member is not part of the structure). Fix this by wraping the test in ifdef, even if I don't really like how the code looks now. The check doesn't have to happen if overlays are disabled at all as the check is always true then.
