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 c05d9a8c7f55a901d9e8ec2a5f0730137bbfea4a Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Thu, 25 Jun 2015 09:35:11 +0100 Subject: [PATCH] ASoC: arizona: Implement stability check for EQ coefficients Specifying unstable coefficients for the EQ can have a severe impact on the audio. This patchs adds a stability check on the coefficients written to the EQ, for this it is necessary to merge the mode control and the coefficients as some coefficients may only be unstable with a certain mode setting so it is ideal if these are always updated in sync.
