The patch ASoC: pcm: save fixed-up hw_params of BE has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.2 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 ae061d2a857f84ad47b77b04c3ad37478651ab6c Mon Sep 17 00:00:00 2001 From: Libin Yang <libin.yang@xxxxxxxxx> Date: Fri, 19 Apr 2019 09:53:12 +0800 Subject: [PATCH] ASoC: pcm: save fixed-up hw_params of BE Some drivers mandate setting up hw params after resuming from system sleep. Since, the hw_params ioctl is not invoked upon resuming, the fixed-up BE dai hw params should be saved so the driver can use it in its resume sequence.
