[PATCH v2 09/29] drm/exynos: switch to drm_*_get(), drm_*_put() helpers

[PATCH v2 09/29] drm/exynos: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

Hi Cihangir,
Thank you for the patch. Unfortunately it does not apply to drm-misc-next. Could
you please resend with conflicts resolved?

OK, I'll send a v3 based on drm-next. And should I drop patches from
v1 already pulled in drm-next?
