Clang static analysis reports this representative issue atomisp-ov2722.c:920:3: warning: 3rd function call argument is an uninitialized value dev_err(&client->dev, "sensor_id_high = 0x%x\n", high); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ high and low are only set when ov2722_read_reg() is successful. Reporting the high value when there is an error is not meaningful. The later read for low is not checked. high and low are or-ed together and checked against a non zero value. Remove the unneeded error reporting for high. Initialize high and low to 0 and use the id check to determine if the reads were successful The later read for revision is not checked. If it fails the old high value will be used and the revision will be misreported. Since the revision is only reported and not checked or stored it is not necessary to return if the read with successful. This makes the ret variable unnecessary so remove it.

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.
