[ Upstream commit 50459501b9a212dbe7a673727589ee105a8a9954 ]
The DMA map functions can fail and should be tested for errors.
If the mapping fails, unmap and return an error.
Fixes: 788838ebe8 ("mwl8k: use pci_unmap_addr{,set}() to keep track of unmap addresses on rx")

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.
