From cac78418e2f54247ea1c141f0cfa1a3f7cbb8889 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Fri, 2 Feb 2024 02:22:35 -0500 Subject: hwmon: (tmp401) 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.
