Replace instances of drm_framebuffer_reference/unreference() with *_get/put() suffixes and drm_dev_unref with *_put() suffix because get/put is shorter and consistent with the kernel use of *_get/put suffixes. Done with following coccinelle semantic patch

Hm yeah, how did this happen? Does cocci really do this, or is that an accident from manually fixing stuff up? -Daniel

Running the spatch from the commit message gives me the correct substitution: @@ -627,7 +627,7 @@ static bool intel_fbdev_init_bios(struct drm_device *dev, ifbdev->preferred_bpp = fb->base.format->cpp[0] * 8; ifbdev->fb = fb;

Probably just finger slip since this is the last chunk before the omitted selftests changes.
Harsha: the "better" way to omit the selftests without hand tuning the patch would be to run the cocci spatch on i915 as normal, and then run "git checkout -- drivers/gpu/drm/i915/selftests/" before committing. It's dangerous to edit patches by hand, or to misrepresent a patch as being the result of a cocci spatch when it's not.
