[PATCH 09/18] mfd: lochnagar-i2c: convert to use maple tree register cache

From: Bo Liu
Date: Tue Feb 06 2024 - 02:15:55 EST


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.
