Sparse issues a warning:
CHECK init/calibrate.c
init/calibrate.c:271:28: warning: symbol 'calibration_delay_done' was not declared. Should it be static?
The actual issue is that it's a __weak symbol that archs can override
(in fact, ARM does so), but no prototype is provided. Let's provide one
to prevent surprises.

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.
