[ Upstream commitdb221412cd] devm_kasprintf() may return NULL on failure of internal allocation thus the assignments are not safe if not checked. On error rza1_pinctrl_register() respectively rza1_parse_gpiochip() return negative values so -ENOMEM in the (unlikely) failure case of devm_kasprintf() should be fine here.

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.
