From: Klaus-Dieter Wacker Date: Wed, 7 Mar 2012 02:06:29 +0000 (+0000) Subject: lcs: Return zero from ccwgroup devs set_offline function X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e427babeefe10023d348e2a3db272612d6e79dc3;p=openwrt%2Fstaging%2Fblogic.git lcs: Return zero from ccwgroup devs set_offline function A return code of non-zero of the devs ccwgroup set_offline function leaves the dev in online state. Having done a partly offlining may leave the dev in unusable state. To make sure the dev is set to offline, zero is returned. A setup trace entry is written in case the offlining steps encountered some trouble. Signed-off-by: Klaus-Dieter Wacker Signed-off-by: Frank Blaschka Signed-off-by: David S.
