Mathias Nyman 1bd8bb7d2d xhci: Don't defer primary roothub registration if there is only one roothub 
The support for xHCI controllers with only one roothub, and the code
to defer primary roothub registation until second roothub got merged
to usb-next for 5.19 at the same time.

commit 873f323618 ("xhci: prepare for operation w/o shared hcd")
commit b7a4f9b5d0 ("xhci: Set HCD flag to defer primary roothub
registration")

These got merged in such a way that the flag to defer primary roothub
registration is set even for xHC controllers with just one roothub.

Fix this by setting the defer flag in a codepath taken only if we have
two roothubs

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.
