In the re-init path xhci_resume() passes 'hcd->primary_hcd' to hci_init(),
however this field isn't initialized by __usb_create_hcd() for a HCD
without secondary controller.
xhci_resume() is called once per xHC device, not per hcd, so the extra
checking for primary hcd can be removed.
Fixes: e0fe986972 ("usb: host: xhci-plat: prepare operation w/o shared hcd")

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.
