ARM: SAMSUNG: 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. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
