[PATCH v2 5/6] drm/i915/display: update audio support based on the available frequencies

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

 



After pruning the sad audio frequency list, if there are no
supported audio frequencies left, audio cannot be supported.
So mark has_audio accordingly.

v2: avoid bitwise operations on bool and use str_yes_no (Jani)
    use intel_display instead of i915
