This reverts commit4c2604a9a6. Asynch probe caused regression in a setup with both Renesas and Intel xHC controllers. Devices connected to the Renesas disconnected shortly after boot. With Asynch probe the busnumbers got interleaved. xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 1 xhci_hcd 0000:04:00.0: new USB bus registered, assigned bus number 2 xhci_hcd 0000:00:14.0: new USB bus registered, assigned bus number 3 xhci_hcd 0000:04:00.0: new USB bus registered, assigned bus number 4 Reason why this commit causes regression is still unknown, but revert it while debugging the 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.
