From: Johannes Berg <johannes.berg@xxxxxxxxx>
The compiler correctly warns:
iwl-agn-tx.c: In function âiwlagn_tx_status_reply_compressed_baâ:
iwl-agn-tx.c:1240: warning: âbitmapâ may be used uninitialized in this function
Move the debug print to the branch that reads the
bitmap, and move the variables too so it's more
obvious where they are needed.
