Adds a shutdown callback to ensure that the XHCI stack is properly shutdown in reboot/shutdown path. In kexec flow, kernel_restart_prepare() performs actions necessary to prepare the system for a restart and invokes device_shutdown. To ensure proper shutdown attach the dwc3 shutdown implementation which mirrors the remove method. $ kexec -e <snip> xhci-hcd xhci-hcd.0.auto: remove, state 1 usb usb1: USB disconnect, device number 1 usb 1-1: USB disconnect, device number 6 xhci-hcd xhci-hcd.0.auto: USB bus 1 deregistered kexec_core: Starting new kernel Signed-off-by: Radhey Shyam Pandey <radhey.shyam.pandey@amd.com> Acked-by: Thinh Nguyen <Thinh.Nguyen@synopsys.com> Link: https://lore.kernel.org/r/1748977771-714153-1-git-send-email-radhey.shyam.pandey@amd.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 reStructuredText 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.
