From ba76d91bc00b5f58ae42991cf9ec97e989bc05a2 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 2 Aug 2016 22:50:28 +0100 Subject: [PATCH] drm/i915: Remove intel_ring_get_tail() Joonas doesn't like the tiny function, especially if I go around making it more complicated and using it elsewhere. To remove that temptation, remove the function!
