Subject: fix kmod_list_prev().
X-Git-Tag: v2~52
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2a70a5d4e0e62313a905378d463bc5857c5eef0b;p=thirdparty%2Fkmod.git

fix kmod_list_prev().

kmod_list_prev() should return NULL if the current element is the
head, not if the previous element is the head. This was likely a copy
& paste error from kmod_list_next().
