Is this a vanilla 2.6.20-rc1, or does it have the patch listed below? This patch is needed to
complete the changes in work struct introduced with .20.

From: Ulrich Kunitz <[email protected]>
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).

John,
This patch should be pushed upstream to 2.6.20. At the moment, the work
struct changes have not yet propagated to wireless-2.6. When they do,
it will be needed there as well.
