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. commit873f323618("xhci: prepare for operation w/o shared hcd") commitb7a4f9b5d0("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 Fixes:873f323618("xhci: prepare for operation w/o shared hcd") Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20220516094850.19788-2-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
