* [PATCH] cfg80211: don't pass pointer to pointer unnecessarily

  To: Johannes Berg, Sara Sharon; +Cc: linux-wireless, Luca Coelho, kernel-janitors

The cfg80211_merge_profile() and ieee802_11_find_bssid_profile() are
a bit cleaner if we just pass the merged_ie pointer instead of a pointer
to the pointer.

This isn't a functional change, it's just a clean up.
