drm/exynos: add vm_ops to specific gem mmaper ...
Changelog v3:
use drm_file's file object instead of gem object's
- gem object's file represents the shmem storage so
process-unique file object should be used instead.
Changelog v2:
call mutex_lock before drm_vm_open_locked is called.
Changelog v1:
This patch makes it takes a reference to gem object when
specific gem mmap is requested. For this, it sets
dev->driver->gem_vm_ops to vma->vm_ops.
And this patch is based on exynos-drm-next-iommu branch of
git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos
