commit 4652fefcda upstream.
When the system is suspended and ptn5150 wakeup interrupt is disabled,
any changes on ptn5150 will only be record in interrupt status
registers and won't fire an IRQ since its trigger type is falling
edge. So the HW interrupt line will keep at low state and any further
changes won't trigger IRQ anymore. To fix it, this will schedule a
work to check whether any IRQ are pending and handle it accordingly.
Fixes: 4ed754de2d ("extcon: Add support for ptn5150 extcon driver")
