Commite0d072782c("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset") introduced a regression in our code since the second backed to probe will now get -EINVAL back from dma_direct_set_offset and will prevent the entire DRM device from probing. Ignore -EINVAL as a temporary measure to get it back working, before removing that call entirely.

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.
