    Subject[PATCH v2 10/13] serial: omap: set dev->drvdata before enabling pm_runtime
    Date
    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.
