Peter Zijlstra 2b60f866d4 compiler_types: Move unused static inline functions warning to W=2 
[ Upstream commit 9818af18db ]

Per Nathan, clang catches unused "static inline" functions in C files
since commit 6863f5643d ("kbuild: allow Clang to find unused static
inline functions for W=1 build").

Linus said:

Here is the change to bump the warning from W=1 to W=2.

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.
