Still doesn't apply, but this might be a git bug, see below:

This patch is not created properly. Did you edit it by hand? If not,
we need to report a bug as the diff is obviously wrong, look at the @@@
line.

Can you update your version of git to see if it's fixed there?

Also, patch tells you that this is broken:

checking file drivers/staging/rtl8192u/ieee80211/ieee80211_softmac.c
patch: **** malformed patch at line 132: skb_put(skb, sizeof(struct ieee80211_authentication));
