[PATCH 41/51] drm/i915: Update ring->emit_request() to take a request structure

John.C.Harrison
2015-02-13T11:49:45Z

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

Updated the ring->emit_request() implementation to take a request instead of a
ringbuf/request pair. Also removed it's use of the OLR for obtaining the
request's seqno.

For: VIZ-5115
