| |
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 wm97xx. Instead of testing work_pending(), use the return value of queue_work() to decide whether to disable IRQ or not.
Only compile tested.

I can take it through the workqueue tree if necessary.
Thanks.
