Subject: [PATCH v2 1/4] msm_serial: Use relative resources for iomem
Date: Tue, 16 Aug 2011 10:52:13 -0700	[thread overview]
Message-ID: <1313517136-27414-2-git-send-email-davidb@codeaurora.org> (raw)
In-Reply-To: <1313517136-27414-1-git-send-email-davidb@codeaurora.org>

Device tree iomem resources are only accessible by index, and not by
name.  The msm_serial devices always have either 1 or 2 iomem
resources, that are always in the same order.  Convert the
platform_get_resource_byname into just platform_get_resource to
facilitate device tree conversion.
