From 9c440cf0c68fa30dc3072b8f1755f2d91863d7d6 Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Fri, 2 Feb 2024 02:14:52 -0500 Subject: [PATCH] hwmon: (emc1403) 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.
