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

@@
expression ex;
@@

(
-drm_framebuffer_unreference(ex);
+drm_framebuffer_put(ex);
|
-drm_dev_unref(ex);
+drm_dev_put(ex);
|
-drm_framebuffer_reference(ex);
+drm_framebuffer_get(ex);
)

Changes in v4:
 -change one instance of *_put to *_get
Changes in v3:
 -Removed changes in selftests
Changes in v2:
 -Added cocinelle patch in log message
 -cc to all driver-specific mailing lists

> Applied now to drm-intel-next-queued, thanks for your patch.

Ok just realized that it doesn't apply on plain drm-intel-next-queued
since that tree doesn't yet have the drm_dev_put function. I've taken that
part out of your patch to unblock it.

Can you pls rebase the remaining parts onto drm-tip from

https://cgit.freedesktop.org/drm/drm-tip

and send a new patch for just the drm_dev_put change? I asked the
drm-intel maintainers to do the backmerge to make sure I can apply this
next week.

Thanks, Daniel
