[PATCH v6 4/5] drm/i915: Transition port type checks to phy checks

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

 



Transition the remaining uses of intel_port_is_* over to the equivalent
intel_phy_is_* functions and drop the port functions.

v5: Fix a call in a debug function that's only called when
    CONFIG_DRM_I915_DEBUG_RUNTIME_PM is on.  (CI)
