Subject: [usb-next PATCH] usb: xhci: skip phys initialization of shared hcd
Date: Wed, 21 Mar 2018 14:12:38 +0800 [thread overview]
Message-ID: <1ece0d5508a00bca67d16e64310a071646b59c7d.1521612280.git.chunfeng.yun@mediatek.com> (raw)
The phys has already been initialized when add primary hcd,
including usb2 phys and usb3 phys also if exist, so needn't
re-parse "phys" property again.
