Hi all,

Today's linux-next merge of the net-next tree got a conflict in
net/mac80211/ibss.c between commit 75a423f493ff ("mac80211: ibss: fix
ignored channel parameter") from the wireless tree and commit
7ca15a0ae865 ("mac80211: allow scanning for 5/10 MHz channels in IBSS")
from the net-next tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
