Tom Rix 544ee7306d media: atomisp: improve error handling in gc2235_detect()
Static analysis reports this representative problem

atomisp-gc2235.c:867:20: warning: The right operand
  of '|' is a garbage value
        id = ((high << 8) | low);
                          ^ ~~~
When gc2235_read_reg() fails, its return val is never written.

For gc2235_detect(), high and low are or-ed and compared
with GC2235_ID, 0x2235.  Initialize both to 0 and skip
checking the read returns, it's errors are not passed up, only
-ENODEV is.

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.
