Subject: [PATCH 1/2] staging: rtl8192u: remove unnecessary function
 implementation

Current implementation of function ieee80211_tkip_null simply returns
back to the caller without any useful instruction executions. This makes
the function call and its implementation unnecessary and should be
removed.
