The change breaks device tree based platforms with PHY device and use usb-role-switch instead of an extcon switch. extcon_find_edev_by_node() will return EPROBE_DEFER if it can not find a device so probing without an extcon device will be deferred indefinitely. Fix this by explicitly checking for usb-role-switch. At least the out-of-tree USB3 support on Apple silicon based platforms using dwc3 with tipd USB Type-C and PD controller is affected by this issue.

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.
