Hello there,


I have a question regarding how to cancel threaded irq handler in a driver's suspend function.
If it's NOT threaded irq, normally you have a work queue, and in the suspend function, you call either cancel_work_sync() or flush_work(), these function will WAIT for the work queue to finish if it's in the middle of something.
However if you use threaded irq, then you don't need a work queue, then in the suspend function, I don't know if there's a simple function that can be used to cancel and wait the thread to finish?


Thanks,
Feng
