[PATCH 4.17 19/45] usb: gadget: udc: renesas_usb3: fix double phy_put()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com>

commit 8223b2f89ca63e203dcb54148e30d94979f17b0b upstream.

This patch fixes an issue that this driver cause double phy_put()
calling. This driver must not call phy_put() in the remove because
the driver calls devm_phy_get() in the probe.

Fixes: 279d4bc64060 ("usb: gadget: udc: renesas_usb3: add support for generic phy")
