mac80211: Modify mesh_set_ht_prot_mode() to have less identation
Determining types of peers is modified to have less indentation. This change is suggested by Johannes. This patch also corrects the reference in comment to IEEE 802.11-2012 version. Signed-off-by: Ashok Nagarajan <ashok@cozybit.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
