The patch

ASoC: wm_adsp: Explicitly set the control access flags in all cases

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.

In the case where the firmware does not tell us the access flags for the control, we let ALSA select a default (READWRITE). But really we should be applying the volatile flag in this case, as we will read the control from the DSP if it is on in this case. This patch explicitly sets the access flags in all cases.

wm_coeff_{read|write}_control were using the control length rather than the length parameter passed to them. This is not causing any issues as the two values are currently always the same, but this needs fixed to allow future improvements.
