[PATCH] drivers: power: always set IRQF_ONESHOT if no primary handler is specified

[PATCH] drivers: power: always set IRQF_ONESHOT if no primary handler is specified

[Saurabh Sengar]

If no primary handler is specified then a default one is assigned which
always returns IRQ_WAKE_THREAD. This handler requires the IRQF_ONESHOT,
because the source of interrupt is not disabled.
