Recent commits1a99de2cb4
and6a590c5f5f
both fixed the same bug in the same manner. Unfortunately git was "smart" enough to merge both changes which resulted in some duplicate code. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Reordered code and comment a bit. Signed-off-by: Wolfgang Denk <wd@denx.de>
