[PATCH 4.14 23/61] usb: dwc2: fix wrong order of phy_power_on and phy_init

[Greg Kroah-Hartman]

From: Heiner Kallweit <hkallweit1@xxxxxxxxx>

commit f9b995b49a07bd0d43b0e490f59be84415c745ae upstream.

Since 1599069a62c6 ("phy: core: Warn when phy_power_on is called before
phy_init") the driver complains. In my case (Amlogic SoC) the warning
is: phy phy-fe03e000.phy.2: phy_power_on was called before phy_init
So change the order of the two calls. The same change has to be done
to the order of phy_exit() and phy_power_off().

Fixes: 09a75e857790 ("usb: dwc2: refactor common low-level hw code to platform.c")
