Subject: drm/i915: Nuke dev_priv->drrs.type
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: c25300f0797be30dd63d74fcc38b5238a2844932
Patch-mainline: v5.19-rc1
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

When we found a downclock mode dev_priv->drrs.type is just a
straight copy of dev_priv->vbt.drrs_type. And in case we
couldn't find a downclock mode can_enable_drrs() won't let
us enable DRRS anyway so the minor distinction between the
two is irrelevant. So let's just nuke dev_priv->drrs.type
and consult the VBT version directly.
