Switch back from devm_request_threaded_irq() to request_threaded_irq() to
avoid races between interrupt handler execution and PM runtime in error
handling code path in probe and in dwc3_omap_remove():

Can't you just call disable_irq() on the exit path instead of removing
devm?

I can. But what will be the benefit from using devm then?

Hmm good point. Probably the least number of code would be to just
do NOAUTOEN before devm_request_irq(), then only do enable_irq()
just before returning from the probe. After all, we don't really
want the irq running until the probe is done.

I think that would leave out the extra handling from the error
path?
