Revision 4c4e45669de475573b15d968a6dca8d00124c9ad authored by Jingoo Han on 23 September 2013, 10:16:57 UTC, committed by Wim Van Sebroeck on 13 October 2013, 18:01:57 UTC
STAGE_CFG bits are defined as [5:4] bits. However, '(((x) & 0x30) << 4)' handles [9:8] bits. Thus, it should be fixed in order to handle [5:4] bits. Signed-off-by: Jingoo Han <jg1.han@samsung.com> Reviewed-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
