Subject: media: i2c: imx214: convert to use maple tree register cache
Author:  Bo Liu <[email protected]>
Date:    Wed Jan 17 04:07:30 2024 +0100

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.
