Subject: common/cmd_misc.c: fix return code of sleep command
X-Git-Tag: KARO-TX-2016-07-05~8
X-Git-Url: https://git.kernelconcepts.de/?p=karo-tx-uboot.git;a=commitdiff_plain;h=a3b5e1ec3e52bd7624e832a612a23fc2dd432abb;ds=sidebyside

common/cmd_misc.c: fix return code of sleep command

-1 is equivalent to CMD_RET_USAGE and makes the sleep command print
its usage information when aborted by <CTRL-C> which is most probably
not intended.
