Christoph Hellwig b8444fa88d dma-direct: don't check swiotlb=force in dma_direct_map_resource 
[ Upstream commit 4268ac6ae5870af10a7417b22990d615f72f77e2 ]

When mapping resources we can't just use swiotlb ram for bounce
buffering.  Switch to a direct dma_capable check instead.

Fixes: cfced786969c ("dma-mapping: remove the default map_resource implementation")

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.
