(Resending the patchset from [1]. Most drivers have already been updated and only two drivers are left.)
Replace all remaining implementations of struct drm_driver.gem_prime_mmap with use drm_gem_prime_mmap(). For each affected driver, put the mmap code into struct drm_gem_object_funcs.mmap. With the latter change in place, create struct file_operations via DEFINE_DRM_GEM_FOPS().
As next steps, drivers can be converted to use drm_gem_prime_mmap() and drm_gem_mmap() (e.g., Tegra). The default mmap code in drm_gem_prime_mmap() can be pushed into affected drivers or a helper function. The gem_prime_mmap hook can probably be removed at some point.
