From 3a254fea70f402859b92a9cd4299ee5de3bbc2f6 Mon Sep 17 00:00:00 2001 From: Peter Chen Date: Tue, 17 Sep 2013 12:37:23 +0800 Subject: usb: chipidea: imx: Add usb_phy_shutdown at probe's error path If not, the PHY will be active even the controller is not in use. We find this issue due to the PHY's clock refcount is not correct due to -EPROBE_DEFER return after phy's init.
