Subject: [PATCH v2 10/13] serial: omap: set dev->drvdata before enabling pm_runtime
Date: Tue, 21 Aug 2012 15:16:08 +0300	[thread overview]
Message-ID: <1345551371-18862-11-git-send-email-balbi@ti.com> (raw)
In-Reply-To: <1345551371-18862-1-git-send-email-balbi@ti.com>

by the time we call our first pm_runtme_get_sync()
after enable pm_runtime, our resume method might
be called. To avoid problems, we must make sure
that our dev->drvdata is set correctly before
our resume method gets called.
