From 6c224da4d79fbb60d087423066c59e8bc8f0a44f Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Fri, 2 Feb 2024 02:18:00 -0500 Subject: [PATCH] hwmon: (lm83) convert to use maple tree register cache 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.
