nvmet_subsys_alloc() returns its pointer or NULL if it fails. We can see three different steps in this function: 1. memory allocation 2. argument check 3. memory allocation for string But now the callers of this function do not seem to handle case 2 by returning -ENOMEM only even if it fails with an invalid parameter. This patch specifies error codes so that caller can pass it to its own caller. Signed-off-by: Minwoo Im <minwoo.im.dev@gmail.com> Reviewed-by: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com>.

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.
