Nicholas Mc Guire 0a87c5333c gpio: pl061: handle failed allocations 
[ Upstream commit df209c43a0 ]

devm_kzalloc(), devm_kstrdup() and devm_kasprintf() all can
fail internal allocation and return NULL. Using any of the assigned
objects without checking is not safe. As this is early in the boot
phase and these allocations really should not fail, any failure here
is probably an indication of a more serious issue so it makes little
sense to try and rollback the previous allocated resources or try to
continue;  but rather the probe function is simply exited with -ENOMEM.

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.
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.
