Subject: [PATCH] power: gpio-charger: Fix checking return value of request_any_context_irq
Date: Mon, 04 Jul 2011 18:04:15 +0800	[thread overview]
Message-ID: <1309773855.2267.1.camel@phoenix> (raw)

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