From 23c7029f376968dbc8d72fd55e60fe2e31c2629b Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Fri, 2 Feb 2024 02:20:07 -0500 Subject: [PATCH] hwmon: (nct7802) 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.
