board_r: return 0 from show_model_r
The show_model_r function should return an int but didn't. Return 0 to indicate inevitable success and avoid the following if it is used: common/board_r.c: In function 'show_model_r': common/board_r.c:531:1: warning: no return statement in function returning non-void [-Wreturn-type] } ^ Cc: Simon Glass <sjg@chromium.org> Signed-off-by: NPaul Burton <paul.burton@imgtec.com> Acked-by: NSimon Glass <sjg@chromium.org>
