Thomas Gleixner e67534bd31 static_call: Replace pointless WARN_ON() in static_call_module_notify() 
[ Upstream commit fe513c2ef0a172a58f158e2e70465c4317f0a9a2 ]

static_call_module_notify() triggers a WARN_ON(), when memory allocation
fails in __static_call_add_module().

That's not really justified, because the failure case must be correctly
handled by the well known call chain and the error code is passed
through to the initiating userspace application.

A memory allocation fail is not a fatal problem, but the WARN_ON() takes
the machine out when panic_on_warn is set.

Replace it with a pr_warn().

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.
