[PATCH v4 08/21] serial: omap: set dev->drvdata before enabling pm_runtime

From: Felipe Balbi
Date: Thu Sep 06 2012 - 08:54:33 EST


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.
