[Intel-gfx] [PATCH 44/55] drm/i915: Update ring->signal() to take a request structure

[John.C.Harrison at Intel.com]

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

Updated the various ring->signal() implementations to take a request instead of
a ring. This removes their reliance on the OLR to obtain the seqno value that
should be used for the signal.

For: VIZ-5115
