Subjectlinux-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
dd730b627cf8ff0b9d20df94fd31b6192b188710 ("Staging: arlan: fixed
unnecessary whitespace style issue in arlan-main.c") from the
staging-next tree.

I fixed it up (see below - this is bigger than is would otherwise be
because there is a conflict with another patch that was previously
reported) and can carry the fix as necessary.
