Subject: [PATCH] USB: ohci-omap: defer probe if PHY is missing
Date: Mon, 2 Jan 2017 22:53:55 +0200 [thread overview]
Message-ID: <20170102205355.18920-1-aaro.koskinen@iki.fi> (raw)
Defer probe if PHY is missing. E.g. on Nokia 770 several modules needs
to be loaded to get the PHY going and ohci-omap should wait for those.
