After a cursory check on the parameters to i915_gem_object_pin_map(), where we return a precise error, if the backend rejects the mapping we always return PTR_ERR(-ENOMEM). Let us also return a more precise error here so we can differentiate between running out of memory and programming errors (or situations where we may be trying different paths and looking for an error from an unsupported map).

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.
