+Subject: drm/amd/display: Use freesync when `DRM_EDID_FEATURE_CONTINUOUS_FREQ` found
+
+From: Mario Limonciello <mario.limonciello@amd.com>
+
+commit 2f14c0c8cae8e9e3b603a3f91909baba66540027 upstream.
+
+The monitor shipped with the Framework 16 supports VRR [1], but it's not
+being advertised.
+
+This is because the detailed timing block doesn't contain
+`EDID_DETAIL_MONITOR_RANGE` which amdgpu looks for to find min and max
+frequencies.  This check however is superfluous for this case because
+update_display_info() calls drm_get_monitor_range() to get these ranges
+already.
+
+So if the `DRM_EDID_FEATURE_CONTINUOUS_FREQ` EDID feature is found then
+turn on freesync without extra checks.
+
+v2: squash in fix from Harry

+Subject: workqueue: Shorten events_freezable_power_efficient name
+
+From: Audra Mitchell <audra@redhat.com>
+
+commit 8318d6a6362f5903edb4c904a8dd447e59be4ad1 upstream.
+
+Since we have set the WQ_NAME_LEN to 32, decrease the name of
+events_freezable_power_efficient so that it does not trip the name length
+warning when the workqueue is created.
