[PATCH 14/32] wireless/ipw2x00: use system_wq instead of dedicated workqueues

From: Tejun Heo
Date: Mon Jan 03 2011 - 08:54:35 EST

With cmwq, there's no reason to use separate workqueues in ipw2x00
drivers. Drop them and use system_wq instead. All used work items
are sync canceled on driver detach.

Only compile tested. Please feel free to take it into the subsystem
tree or simply ack - I'll route it through the wq tree.

Thanks.
