Subject: [PATCH 1/5] aoa: feature gpio layer: fix IRQ access
Date: Tue, 18 Jul 2006 19:28:42 +0200	[thread overview]
Message-ID: <20060718173012.532719000@sipsolutions.net> (raw)
In-Reply-To: 20060718172841.046446000@sipsolutions.net

The IRQ rework caused some hiccups here, in some cases we call
get_irq without a device node. This patch makes it catch that
case and return NO_IRQ when it happens, along with changing the
place where the irq is checked to check for NO_IRQ instead of -1.
