Dmitry Torokhov a333f3f2a2 Input: do not use WARN() in input_alloc_absinfo() 
[ Upstream commit 100294cee9 ]

Some of fuzzers set panic_on_warn=1 so that they can handle WARN()ings
the same way they handle full-blown kernel crashes. We used WARN() in
input_alloc_absinfo() to get a better idea where memory allocation
failed, but since then kmalloc() and friends started dumping call stack on
memory allocation failures anyway, so we are not getting anything extra
from WARN().

Because of the above, let's replace WARN with dev_err(). We use dev_err()
instead of simply removing message and relying on kcalloc() to give us
stack dump so that we'd know the instance of hardware device to which we
were trying to attach input device.

README 

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
