usb_phy_roothub_exit() should return the error code from the phy_exit()
call if exiting the PHY failed.
However, since a wrong variable is used usb_phy_roothub_exit() currently
always returns 0, even if one of the phy_exit calls returned an error.
Clang also reports this bug:
kernel/drivers/usb/core/phy.c:114:8: warning: explicitly assigning value of
variable of type 'int' to itself [-Wself-assign] error, forbidden
warning: phy.c:114
Fix this by assigning the error code from phy_exit() to the "ret"
variable to propagate the error correctly.
Fixes: 07dbff0ddb ("usb: core: add a wrapper for the USB PHYs on the HCD")

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
