[PATCH] drm/bridge: lt9211: Convert to use maple tree register cache

Mark Brown broonie at kernel.org
Sun Oct 1 10:24:49 UTC 2023


The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache.
