Day Date: Tue, 29 Apr 2008 07:59:29 +0000 (-0700) Subject: lists: add "const" qualifier to first arg of list_splice() operations X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=95d8c365b2df2adb904963333a93b15414403ed1;p=openwrt%2Fstaging%2Fblogic.git lists: add "const" qualifier to first arg of list_splice() operations Since neither the list_splice() nor __list_splice() routines modify their first argument, might as well declare them "const".
