Clang points out that the error handling in ov02a10_s_stream() is
broken, and just returns a random error code:
drivers/media/i2c/ov02a10.c:537:6: warning: variable 'ret' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
if (ov02a10->streaming == on)
^~~~~~~~~~~~~~~~~~~~~~~~
drivers/media/i2c/ov02a10.c:568:9: note: uninitialized use occurs here
return ret;
^~~
drivers/media/i2c/ov02a10.c:537:2: note: remove the 'if' if its condition is always false
if (ov02a10->streaming == on)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If streaming is already on, leave it that way and return success.

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.
