Subject: [PATCH] media: i2c: isl7998x: convert to use maple tree register cache
Date: Tue, 16 Jan 2024 22:09:10 -0500 [thread overview]
Message-ID: <20240117030910.2790-1-liubo03@inspur.com> (raw)
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.
