[PATCH 08/10] drm/i915: Expect child dev size of 22 bytes for VBT < 106

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

My 830 has VBT version 105 with child device size of 22 bytes.
Let's assume that's correct and adjust our expectations.
