[PATCH 1/2] drm/i915: Create a intel_encoder_find_connector helper function.

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

 



This makes the code in intel_sanitize_encoder slightly more readable.
This was meant to be addressed in fd6bbda9c7a4, but I missed that
review comment.

Fixes: fd6bbda9c7a4 ("drm/i915: Pass crtc_state and connector_state to encoder functions")
