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 be6ac0a9ced99403c435b2b2fe9ac4bd55749823 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 11 Sep 2018 06:51:45 +0000 Subject: [PATCH] ASoC: soc-core: add snd_soc_is_matching_component() To find (CPU/)Codec/Platform, we need to find component first (= on CPU/Codec/Platform), and find DAI from it (= CPU/Codec). These are similar operation but difficult to be simple, and has many duplicate code to finding component. This patch adds new snd_soc_is_matching_component(), and reduce duplicate codes.
