From 291bfb928863d496e25c785e132a8fbfb32341a8 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 19 Apr 2018 12:14:10 +0100 Subject: [PATCH] ASoC: topology: Revert recent changes while boot errors are investigated Krzysztof Kozlowski reported a NULL dereference in _instantiate_card() on Odroid XU3 and XU boards which he bisected to 45f8cb57da0d7 (ASoC: core: Allow topology to override machine driver FE DAI link config). Revert that commit for now, along with f11a5c27f928 (ASoC: core: Add name prefix for machines with topology rewrites) due to dependency issues, in order to keep things booting cleanly in -next.
