In function sram_reserve_regions(), the value of return variable ret should be negative on failures. However, the value of ret may be 0 even if the call to devm_kstrdup() returns a NULL pointer. This patch explicitly assigns "-ENOMEM" to ret on the path that devm_kstrdup() fails.

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.
