This code doesn't check for NULL consistently and it generates a Smatch
warning:
drivers/media/i2c/sr030pc30.c:575 sr030pc30_base_config()
error: we previously assumed 'info->pdata' could be null (see line 572)
Fortunately, "info->pdata" can't be NULL to that check can be removed.
The other thing is that if "ret" is an error code here, then we don't
want to do the next call to cam_i2c_write(), so actually let's flip that
test around and return the error. This is more of a theoretical issue
than something which is likely to affect real life.

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.
