Subject: [PATCHv3 11/17] i2c: omap: switch to platform_get_irq()
Date: Fri, 29 Jun 2012 15:43:31 +0530	[thread overview]
Message-ID: <1340964817-8599-12-git-send-email-shubhrajyoti@ti.com> (raw)
In-Reply-To: <1340964817-8599-1-git-send-email-shubhrajyoti@ti.com>

From: Felipe Balbi <balbi@ti.com>

that's a nice helper from drivers core which
will give us the exact IRQ number, instead
of a pointer to an IRQ resource.
