From e02a4ccbeced64aa10f4e99683c721ec43e993c1 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 21 Jul 2023 17:31:36 +0100 Subject: regmap: Remove dynamic allocation warnings for rbtree and maple Thanks to Dan and Guenter's very prompt updates of the rbtree and maple caches to support GPF_ATOMIC allocations and since the update shook out a bunch of users at least some of whom have been suitably careful about ensuring that the cache is prepoulated so there are no dynamic allocations after init let's revert the warnings.
