Subject: [PATCH] ieee80211softmac: Fix errors related to the work_struct changes

The signature of work functions changed recently from a context
pointer to the work structure pointer. This caused a problem in
the ieee80211softmac code, because the ieee80211softmac_assox_work
function has  been called directly with a parameter explicitly
casted to (void*). This compiled correctly but resulted in a
softlock, because mutex_lock was called with the wrong memory
address. The patch fixes the problem. Another issue was a wrong
call of the schedule_work function. Softmac works again and this
fixes the problem I mentioned earlier in the zd1211rw rx tasklet
patch. The patch is against Linus' tree (commit af1713e0).
