Ville Syrjälä 1b9bd09630 drm/i915: Do not create a new max_bpc prop for MST connectors ... We're not allowed to create new properties after device registration so for MST connectors we need to either create the max_bpc property earlier, or we reuse one we already have. Let's do the latter apporach since the corresponding SST connector already has the prop and its min/max are correct also for the MST connector. The problem was highlighted by commit 4f5368b554 ("drm/kms: Catch mode_object lifetime errors") which results in the following spew: [ 1330.878941] WARNING: CPU: 2 PID: 1554 at drivers/gpu/drm/drm_mode_object.c:45 __drm_mode_object_add+0xa0/0xb0 [drm] ...
