Commit69bec72598("USB: core: let USB device know device node") added support for attaching devicetree node for USB devices. Those nodes are children of their USB host controller. However Exynos EHCI and OHCI driver bindings already define child-nodes for each physical root hub port and assigns respective PHY controller and parameters to them. Those bindings predates support for USB device tree nodes. To mitigate the side-effects of the conflict between those bindings, lets reset Exynos host controller of_node pointer before registering it to USB subsystem. This fixes the issue raised by the commit01fdf179f4("usb: core: skip interfaces disabled in devicetree"), which incorrectly disabled some devices on Exynos based boards.

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.
