From bc4730a3499c9350aa2ce973109252d56c5e5386 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 8 Sep 2011 21:18:49 +0200 Subject: [PATCH 2/5] s3c-adc: Fix mux bit modification in s3c_adc_select The mux bits in the adccon register should be cleared only if muxing is really done in ADCCON and not another register. This patch introduces a conditional for this.
