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 288b8da7e992f0b86b283f98e92885781ffdcaee Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Thu, 3 Nov 2016 01:03:17 +0800 Subject: [PATCH] ASoC: topology: Support topology file of ABI v4 Users start to use topology ABI from v4. ABI v5 updated existing manifest and PCM elements. Two previous patches can support these ABI updates in a backward compatible way. So if the topology file from user space is generated by ABI v4, kernel will no longer quit but continue parsing.
