Subject: drm/i915: Remove warning from the rps worker
Git-commit: 4b8bcaf8a6d6ab5db51e30865def5cb694eb2966
Patch-mainline: v5.15-rc4
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Alt-commit: a837a0686308d95ad9c48d32b4dfe86a17dc98c2
In commit 4e5c8a99e1cb ("drm/i915: Drop i915_request.lock requirement
for intel_rps_boost()"), we decoupled the rps worker from the pm so
that we could avoid the synchronization penalty which makes the
assertion liable to run too early. Which makes warning invalid hence
removed.
