The patch ASoC: soc-core: tidyup for snd_soc_dapm_new_controls() has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4 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 b8ba3b572c70c8559ef76c1e0ca02e7b05126e8c Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Wed, 7 Aug 2019 10:30:53 +0900 Subject: [PATCH] ASoC: soc-core: tidyup for snd_soc_dapm_new_controls() snd_soc_dapm_new_controls() registers controls by using for(... i < num; ...). It means if widget was NULL, num should be zero. Thus, we don't need to check about widget pointer. This patch also cares missing return value.
