[Resending to get through vger's address checks - sorry for duplicate]

Hi John,

Today's linux-next merge of the wireless-next tree got a conflict in
drivers/net/wireless/b43/dma.c between commit 3db1cd5c05f3 ("net: fix
assignment of 0/1 to bool variables") from the net-next tree and commit
bad691946966 ("b43: avoid packet losses in the dma worker code") from the
wireless-next tree.

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

The newly created tx_queue_stopped array element assignments should be
changed form 0/1 to false/true as well (here and in main.c).
