already_uses() is unnecessarily chatty. `modprobe i915` yields 491 messages like: [ 64.108744] i915 uses drm! This is a normal situation, and isn't worth all the log entries. NOTE: I've preserved the "does not use %s" messages, which happens less often, but does happen. Its not clear to me what it tells a reader, or what info might improve the pr_debug's utility.

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.
