videodev.ko and v4l2-common.ko driver are built under
the same conditions. Therefore, it doesn't make much sense
to split them in two different modules.
Splitting v4l2-common to its own driver was done many years ago:

V4L/DVB (7115): Fix bug #9833: regression when compiling V4L without I2C
Back then, the subsystem organization was different and the module split
was needed. However, with the current organization, there is no issue
compiling V4L2 with I2C as y/m/n.
This commit makes v4l2-common part of our V4L2 core driver (videodev.ko).

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.
