[PATCH 29/53] drm/i915: Update add_request() to take a request structure

John.C.Harrison
2015-02-19T17:18:37Z

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

Now that all callers of i915_add_request() have a request pointer to hand, it is
possible to update the add request function to take a request pointer rather
than pulling it out of the OLR.

For: VIZ-5115
