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 25f7b701c20db3e9ae09e28dd652949bd977e5cd Mon Sep 17 00:00:00 2001 From: Arnaud Pouliquen Date: Tue, 3 Jan 2017 16:52:51 +0100 Subject: [PATCH] ASoC: core: add optional pcm_new callback for DAI driver During probe, DAIs can need to perform some actions that requests the knowledge of the pcm runtime handle. The callback is called during DAIs linking, after PCM device creation. For instance this can be used to add relationship between a DAI pcm control and the pcm device.
