From 47e26b1bf91ddef69f4a3892815c857db094cef9 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sat, 17 Jul 2010 01:06:04 +0200 Subject: cmd_usage(): simplify return code handling Lots of code use this construct: cmd_usage(cmdtp); return 1; Change cmd_usage() let it return 1 - then we can replace all these ocurrances by return cmd_usage(cmdtp); This fixes a few places with incorrect return code handling, too.
