You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark From d1e81428826221d7ff8e4d83db784d099cd232a7 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 18 Aug 2016 19:32:59 +0100 Subject: [PATCH] ASoC: core: Clean up DAPM before the card debugfs Both the card and DAPM cleanups recursively delete their debugfs directories. Since the DAPM debugfs subdirectory for the card is located within the card debugfs this means we end up trying to double free the DAPM subdirectory. Reorder the cleanup to free the card debugfs after we've cleaned up DAPM and it has deleted its own subdirectory.
