Hi Sebastian,

Thank you for the patch.

Given that you only add four lines of code here, and given that the enabled 
bit is unused here, I'd just squash this patch with the one that makes use of 
the enabled bit.

Atomic KMS drivers should store state in the state structure, not the KMS 
objects themselves. Beside, how does this differ from the CRTC state enable 
and active fields ?
