Subject: New sparse warning in net/mac80211/debugfs_sta.c

commit 0795af5729b18218767fab27c44b1384f72dc9ad
Author: Joe Perches <joe@...ches.com>

    [NET]: Introduce and use print_mac() and DECLARE_MAC_BUF()
    
    This is nicer than the MAC_FMT stuff.

Introduced:
net/mac80211/debugfs_sta.c: In function ‘ieee80211_sta_debugfs_add’:
net/mac80211/debugfs_sta.c:211: warning: statement with no effect

Does print_mac modify the mac buffer in-place, or return a new buffer?

Harvey
