[PATCH 14/25] rfkill: don't use [delayed_]work_pending()

From: Tejun Heo
Date: Fri Dec 21 2012 - 21:02:04 EST


There's no need to test whether a (delayed) work item in pending
before queueing, flushing or cancelling it. Most uses are unnecessary
and quite a few of them are buggy.

Remove unnecessary pending tests from rfkill. Only compile
tested.

Please let me know how this patch should be routed. I can take it
through the workqueue tree if necessary.

Thanks.
