[ Upstream commit 4831ca9e4a8e48cb27e0a792f73250390827a228 ]
The allocation for elem may fail (especially because we're using
GFP_ATOMIC) so best to check for a null return. This fixes a potential
null pointer dereference when assigning elem->pool.
Detected by CoverityScan CID#1357507 ("Dereference null return value")
Fixes: 8700e3e7c485 ("Soft RoCE driver")

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.
