[ Upstream commit e1a7418529e33bc4efc346324557251a16a3e79b ]
Currently the allocation of priv->oldaddr is not null checked which will
lead to subsequent errors when accessing priv->oldaddr. Fix this with
a null pointer check and a return of -ENOMEM on allocation failure.
Detected with Coccinelle:
drivers/staging/rtl8192u/r8192U_core.c:1708:2-15: alloc with no test,
possible model on line 1723
Fixes: 8fc8598e61f6 ("Staging: Added Realtek rtl8192u driver to staging")

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.
