Dan Carpenter 8feca62590 RDMA/mlx4: Prevent shift wrapping in set_user_sq_size()
[ Upstream commit d50b3c73f1ac20dabc53dc6e9d64ce9c79a331eb ]

The ucmd->log_sq_bb_count variable is controlled by the user so this
shift can wrap.  Fix it by using check_shl_overflow() in the same way
that it was done in commit 515f60004ed9 ("RDMA/hns: Prevent undefined
behavior in hns_roce_set_user_sq_size()").

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.
