From: Mark Brown Date: Fri, 26 Nov 2010 17:23:42 +0000 (+0000) Subject: ASoC: Enable rbtree compression for WM8994/58 register cache X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2e19b0c8c21cb06eb5b902588c30ae0529ce8ec3;p=linux-beck.git ASoC: Enable rbtree compression for WM8994/58 register cache The WM8994 and WM8958 register map is relatively sparse so benefits from compression. The rbtree compression gives better results than LZO for both memory and CPU consumption on a map as sparse as this.
