John Stultz 4ccc03e28e driver core: Use dev_warn() instead of dev_WARN() for deferred_probe_timeout warnings 
In commit c8c43cee29 ("driver core: Fix
driver_deferred_probe_check_state() logic") and following
changes the logic was changes slightly so that if there is no
driver to match whats found in the dtb, we wait the sepcified
seconds for modules to be loaded by userland, and then timeout,
where as previously we'd print "ignoring dependency for device,
assuming no driver" and immediately return -ENODEV after
initcall_done.

However, in the timeout case (which previously existed but was
practicaly un-used without a boot argument), the timeout message
uses dev_WARN(). This means folks are now seeing a big backtrace
in their boot logs if there a entry in their dts that doesn't
have a driver.

To fix this, lets use dev_warn(), instead of dev_WARN() to match
the previous error path.

README 

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.
