Zijun Hu 63559ba807 usb: musb: sunxi: Fix accessing an released usb phy 
commit 498dbd9aea upstream.

Commit 6ed05c68cb ("usb: musb: sunxi: Explicitly release USB PHY on
exit") will cause that usb phy @glue->xceiv is accessed after released.

1) register platform driver @sunxi_musb_driver
// get the usb phy @glue->xceiv
sunxi_musb_probe() -> devm_usb_get_phy().

2) register and unregister platform driver @musb_driver
musb_probe() -> sunxi_musb_init()
use the phy here
//the phy is released here
musb_remove() -> sunxi_musb_exit() -> devm_usb_put_phy()

3) register @musb_driver again
musb_probe() -> sunxi_musb_init()
use the phy here but the phy has been released at 2).
...

Fixed by reverting the commit, namely, removing devm_usb_put_phy()
from sunxi_musb_exit().

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
