[PATCH 039/120] drm/amd/display: Move stream validations into seperate function.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andrey Grodzovsky <Andrey.Grodzovsky@xxxxxxx>

Stateless streams validations (not require resource population)
moved into hook to be called directly from DM.

Call dc_validate_stream be before validate_with_context for
non Linux APIs
