Subject: [patch] input/tps6507x-ts: a couple work queue cleanups
Date: Tue, 01 Jun 2010 15:27:45 +0000	[thread overview]
Message-ID: <20100601152744.GN5483@bicker> (raw)

1) Use msecs_to_jiffies() instead of calculating by hand.
2) Call cancel_delayed_work_sync() instead of cancel_delayed_work() 
   followed by a separate flush_workqueue().
3) Remove the "tsc->wq = 0;"  Sparse complains about that because
   tsc->wq is a pointer, not an int.  It's not needed because we just
   free the pointer anyway.
