Subject: [PATCH] drm/i915: No need for RING_MAX_NONPRIV_SLOTS space
Git-commit: d6242aeb48d741eb7c1559cdb95d368de04466bd
Patch-mainline: v4.15-rc1
References: FATE#322643 bsc#1055900

Now that we write RING_FORCE_TO_NONPRIV registers directly to hardware,
[commit 32ced39 ("drm/i915: Transform whitelisting WAs into a simple reg
write")] there is no need to save space for them in the list of context
workarounds.

V2: Refer to previous commit in commit message (Michel)
