Hi Mark,
This patchset fixes broken lpass-platform driver in v4.9-rc1, and also
fixes problem while using lpass as kernel module.
There is also a cleanup patch in this series just to tidy up the code
in the same area where there is regression.
Tested this patchset with msm8916 codec patchset in linux-next on
v4.9-rc1 on DB410c.
Without this patchset lpass-platform driver can not play audio or
even load/unload as module.
Thanks,
srini
Changes since v2:
- reordered fix so that it can go into next rc, suggested by Mark.
- Added Acks from Kenneth

Holding a single private pointer to it in global lpass_data will not work, because it would be overwritten by for each pcm instance. This code was breaking playback when we have both playback and capture pcm streams, as playback settings are over written by capture settings. Fix this by moving channel allocation logic out of pcm_new to pcm_open so that we can store the stream specific information in private_data of snd_pcm_runtime.

Thanks, Mark >From 022d00ee0b55e6cd49048acadb9bf76c37e538d8 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Date: Mon, 31 Oct 2016 11:25:43 +0000 Subject: [PATCH] ASoC: lpass-platform: Fix broken pcm data usage This patch fixes lpass-platform driver which was broken in v4.9-rc1. lpass_pcm_data data structure holds information specific to stream. Holding a single private pointer to it in global lpass_data will not work, because it would be overwritten by for each pcm instance. This code was breaking playback when we have both playback and capture pcm streams, as playback settings are over written by capture settings. Fix this by moving channel allocation logic out of pcm_new to pcm_open so that we can store the stream specific information in private_data of snd_pcm_runtime.

* Applied "ASoC: lpass-platform: use dma_ch instead of rdma_ch/wrdma_ch" to the asoc tree @ 2016-10-31 18:31 ` Mark Brown 0 siblings, 0 replies; 8+ messages in thread From: Mark Brown @ 2016-10-31 18:31 UTC (permalink / raw) To: Srinivas Kandagatla; +Cc: Kenneth Westfield, Mark Brown The patch ASoC: lpass-platform: use dma_ch instead of rdma_ch/wrdma_ch has been applied to the asoc tree at git://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.
