Palams extcon IRQs are nested threaded and wired to the Palmas
inerrupt controller. So, this flag is not required for nested
irqs anymore, since commit 3c646f2c6aa9 ("genirq: Don't suspend
nested_thread irqs over system suspend") was merged. However, the
fix missed a stray flag causing the following crash on resume on
BeagleBoard-X15 platform:

Hi Nishanth,
Don't need to add the IRQF_ONE_SHOT flag for "palmas_usb_id" interrupt?
If don't need it, I'll merge it on extcon-fixes and then send the pull request for rc cycle.
Best Regards,
Chanwoo Choi

I will resumbit a v2 with updates from Lee as well.
