The patch ASoC: omap: Delete the obsolete omap-pcm has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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 cfb53a56d1024bfa547a55ba599a19f882253003 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi <peter.ujfalusi@xxxxxx> Date: Wed, 9 May 2018 14:03:56 +0300 Subject: [PATCH] ASoC: omap: Delete the obsolete omap-pcm All DAI drivers are now using the new sdma-pcm platform driver. The omap-pcm can be removed from the tree, but we need to keep the SND_OMAP_SOC Kconfig option until the relevant defconfigs are updated to avoid regression due to missing audio.
