commit 37e00703228ab44d0aacc32a97809a4f6f58df1b upstream.
Use common wrappers operating directly on the struct sg_table objects to
fix incorrect use of statterlists related calls. dma_unmap_sg() function
has to be called with the number of elements originally passed to the
dma_map_sg() function, not the one returned in sgtable's nents.

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.
