[Intel-gfx] [PATCH 24/55] drm/i915: Update render_state_init() to take a request structure

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

Updated the two render_state_init() functions to take a request pointer instead
of a ring. This removes their reliance on the OLR.

v2: Rebased to newer tree.
