Subject: [PATCH 5/7] dwc2: remove redundant D0 power state set
Date: Thu, 30 May 2013 18:24:07 +0800 [thread overview]
Message-ID: <1369909447-36368-1-git-send-email-wangyijing@huawei.com> (raw)
Pci_enable_device() will set device power state to D0,
so it's no need to do it again in dwc2_driver_probe().
