AFAIU may below patch also solves above issue implicitly.

Besides that +1 for below Ram comment, it would be better if such type of

DP MST support
(https://patchwork.freedesktop.org/series/81289/)
and HDCP over MST misc series.

drm/i915/hdcp: Update CP property in update_pipe
drm/i915/hotplug: Handle CP_IRQ for DP-MST
drm/i915/hdcp: DP MST transcoder
LED.
This caught with DP MST setup, when disabling HDCP on a connector
sets the crtc state need_modeset to true for all crtc driving
the other DP-MST topology connectors.

IMHO intel_crtc_check_fastset() make sure that every crtc_state->mode_changed
will not turn up to a modeset. It seems it is already being taken care.

There can be situation when DP MST connector is created without
mst modeset being done, in those cases connector->encoder will be
NULL. MST connector->encoder initializes after modeset.
Don't enable HDCP in such cases to prevent any crash.
