The patch ASoC: soc-core: merge snd_pcm_ops member to component driver 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. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From e2cb4a14541dba3587bb78e0f62da27a0e1ad399 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Wed, 2 Oct 2019 14:30:48 +0900 Subject: [PATCH] ASoC: soc-core: merge snd_pcm_ops member to component driver Current snd_soc_component_driver has snd_pcm_ops, and each driver can have callback via it (1). But, it is mainly created for ALSA, thus, it doesn't have "component" as parameter for ALSA SoC (1)(2). Thus, each callback can't know it is called for which component. Thus, each callback currently is getting "component" by using snd_soc_rtdcom_lookup() with driver name (3). --- ALSA SoC --- ... if (component->driver->ops && component->driver->ops->open) (1) return component->driver->ops->open(substream); ... --- driver --- (2) static int xxx_open(struct snd_pcm_substream *substream) { struct snd_soc_pcm_runtime *rtd = substream->private_data; (3) struct snd_soc_component *component = snd_soc_rtdcom_lookup(..); ... } It works today, but, will not work in the future if we support multi CPU/Codec/Platform, because 1 rtd might have multiple components which have same driver name. To solve this issue, each callback needs to be called with component. We already have many component driver callback. This patch copies each snd_pcm_ops member under component driver, and having "component" as parameter. --- ALSA SoC --- ... if (component->driver->open) => return component->driver->open(component, substream); ... --- driver --- => static int xxx_open(struct snd_soc_component *component, struct snd_pcm_substream *substream) { ... } *Note* Only Intel skl-pcm has .get_time_info implementation, but ALSA SoC framework doesn't call it so far. To keep its implementation, this patch keeps .get_time_info, but it is still not called. Intel guy need to support it in the future.
