[PATCH RESEND] power: generic-adc-battery: Fix checking return value of request_any_context_irq

[Axel Lin <axel.lin@ingics.com>]

On failure, request_any_context_irq() returns a negative value.
On success, it returns either IRQC_IS_HARDIRQ or IRQC_IS_NESTED.

Nobody picks up this patch, so resend it.
I think this patch is for 3.7.
