From cac3d77098d6c3b6badb1842eb1093a31843c9ca Mon Sep 17 00:00:00 2001 From: Bo Liu Date: Tue, 6 Feb 2024 02:13:12 -0500 Subject: [PATCH] mfd: stmfx: 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.
