Subject: drm/i915: Fix up some DRRS type checks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 2953d732745656982bf8b45ae5bdc89041bb7897
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

Only seamless DRRS needs the frontbuffer tracking, so check for that.
Also use != consistently instead of randomly picking < as the comparison
operator.
