From 925b2c3f6b6f81a5405a647b381d12a93f06a730 Mon Sep 17 00:00:00 2001 From: wangkaiyuan Date: Mon, 18 Mar 2024 14:42:16 +0800 Subject: [PATCH] tty: serial: sc16is7xx: 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.
