Our driver makes a typical use of CMA, with GEM object allocated as GEM CMA objects. Use DRM_GEM_CMA_VMAP_DRIVER_OPS to describe the ops instead of duplicating them. Because DRM_GEM_CMA_VMAP_DRIVER_OPS implements a gem_create_object op which sets per-object funcs (drm_cma_gem_default_funcs), we can also get rid of free_object_unlocked and gem_vm_ops, which are superseded by the object funcs.

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.
