Randy Dunlap a7b81d0d2e usb: usbip: vhci_hcd: protect shift size
commit 718bf42b11 upstream.

Fix shift out-of-bounds in vhci_hcd.c:

  UBSAN: shift-out-of-bounds in ../drivers/usb/usbip/vhci_hcd.c:399:41
  shift exponent 768 is too large for 32-bit type 'int'

Fixes: 03cd00d538 ("usbip: vhci-hcd: Set the vhci structure up to work")

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.
