Christoph Hellwig 06f55fd2d2 x86/amd_gart: fix unmapping of non-GART mappings 
In many cases we don't have to create a GART mapping at all, which
also means there is nothing to unmap.  Fix the range check that was
incorrectly modified when removing the mapping_error method.

Fixes: 9e8aa6b546 ("x86/amd_gart: remove the mapping_error dma_map_ops method")

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.
