From: Manasi Navare <[email protected]> [ Upstream commit 62929726ef0ec72cbbe9440c5d125d4278b99894 ]
VRR capable property is not attached by default to the connector It is attached only if VRR is supported. So if the driver tries to call drm core set prop function without it being attached that causes NULL dereference.
