X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dcbb5a54f6e3984efa24772394f2225b11495c55;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] swsusp: clean up suspend header

Remove some things that are no longer used or defined elsewhere from suspend.h
and make the inline version of software_suspend() return the right error code.
