Tom Rix a135b366c3 drm/bridge: sil_sii8620: initialize return of sii8620_readb 
[ Upstream commit 02cd2d3144 ]

clang static analysis flags this error

sil-sii8620.c:184:2: warning: Undefined or garbage value
  returned to caller [core.uninitialized.UndefReturn]
        return ret;
        ^~~~~~~~~~

sii8620_readb calls sii8620_read_buf.
sii8620_read_buf can return without setting its output
pararmeter 'ret'.

So initialize ret.

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.
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.
