Subject: linux-next: manual merge of the staging-next tree with the net tree

Hi Greg,

Today's linux-next merge of the staging-next tree got a conflict in
drivers/staging/arlan/arlan-main.c between commit
22bedad3ce112d5ca1eaf043d4990fa2ed698c87 ("net: convert multicast list to
list_head") from the net tree and commit
8db2022b08e232bb237b2162f03ff5f6e7c0c35e ("staging: arlan: fix errors
reported by checkpatch.pl tool") from the staging-next tree.

I fixed it up (see below) and can carry the fix as necessary.
