From 233538501f707b0176f09af7039fec1e3fcac6e7 Mon Sep 17 00:00:00 2001 From: Janusz Krzysztofik Date: Tue, 2 Nov 2010 15:50:32 +0100 Subject: [PATCH 1/5] ASoC: OMAP: fix OMAP1 compilation problem In the new code introduced with commit cf4c87abe238ec17cd0255b4e21abd949d7f811e, "OMAP: McBSP: implement McBSP CLKR and FSR signal muxing via mach-omap2/mcbsp.c", the way omap1 build is supposed to bypass omap2 specific functionality doesn't optimize out all omap2 specific stuff. This breaks linking phase for omap1 machines, giving "undefined reference to `omap2_mcbsp1_mux_clkr_src'" and "undefined reference to `omap2_mcbsp1_mux_fsr_src'" errors. Fix it. Created and tested against linux-2.6.37-rc1.
