Subject: bcm43xx-softmac broken on 2.6.20-rc2

This is a heads-up for anyone wishing to use bcm43xx-softmac on Linus's git tree, which is now at
v2.6.20-rc2. There are two serious bugs in that code. Fixes are found below.

The first bug is the result of changes in work queues. The second is the result of a typo that locks 
a mutex when it should unlock it.

These fixes have been pushed up stream, but neither has made it to Linus.
