Subject: [PATCH] mac80211: don't check if key is NULL in ieee80211_key_link()
Git-commit: 753a9a729f84e22b3726f5bf61e1a9b59712d04f
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
We already assume that key is not NULL and dereference it in a few
other places before we check whether it is NULL, so the check is
unnecessary. Remove it.
