Axel Lin f8c63918c9 gpio-charger: Fix checking return value of request_any_context_irq
request_any_context_irq() returns a negative value on failure.
On success, it returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED.

Benson Leung f10513de2a gpio-charger: Add gpio_charger_resume
Gpio charger should notify if the gpio state had changed
during suspend. This will send a CHANGED event each time
the system resumes, ensuring a plug/unplug of the charger
is not missed.

Lars-Peter Clausen 26eb387265 gpio-charger: Fix potential race between irq handler and probe/remove
This patch fixes a potential race between the irq handler and the probe
and remove functions.

The irq should not be requested before the chargers power_supply has been
registered and has to be freed before the power_supply is unregistered,
otherwise it is possible that the irq fires while the power_supply is not
initialized yet or has already been freed.

While we are at it replace request_irq with request_any_context_irq.
