From c479c1361ade3cf2346f41a922b85373ddff8a26 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Mon, 1 Jul 2013 09:09:23 -0400 Subject: cmd_bootm.c: Correct check/return for unsupported sub-command MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With the do_bootm_states re-organization, we have the call to any potential sub-commands in a single spot. If one fails, we can then stop right there and return to the caller. Prior to these calls we have already ensured that ret is zero so we will not be returning this error for some other case.
