Colin Ian King cf20553518 media: cx231xx: fix potential sign-extension overflow on large shift 
[ Upstream commit 32ae592036d7aeaabcccb2b1715373a68639a768 ]

Shifting the u8 value[3] by an int can lead to sign-extension
overflow. For example, if value[3] is 0xff and the shift is 24 then it
is promoted to int and then the top bit is sign-extended so that all
upper 32 bits are set.  Fix this by casting value[3] to a u32 before
the shift.

Detected by CoverityScan, CID#1016522 ("Unintended sign extension")

Fixes: e0d3bafd0258 ("V4L/DVB (10954): Add cx231xx USB driver")

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
