The patch ASoC: soc-core: remove snd_soc_rtdcom_del_all() has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. 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.

Thanks, Mark >From 353e16bf60458fae5927cf04ff668fc152fff465 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Thu, 12 Sep 2019 13:42:44 +0900 Subject: [PATCH] ASoC: soc-core: remove snd_soc_rtdcom_del_all() If we can use devm_kzalloc(rtd->dev, xxx) for rtdcom, we don't need to call snd_soc_rtdcom_del_all() for kfree(). This patch uses devm_kzalloc(rtd->dev, xxx) for rtdcom, and remove snd_soc_rtdcom_del_all().
