Message-Id: <1283959907-8159-1-git-send-email-gbean@codeaurora.org>
Date: Wed, 8 Sep 2010 08:31:46 -0700
From: Gregory Bean <gbean@...eaurora.org>

Subject: [PATCH 1/2 v3] msm: Install the Google-Android gpio driver.
As part of the ongoing effort to converge on a common code base,
adopt the Google-Android msmgpio driver, as it has a stronger pedigree
than the previous submission from codeaurora.
