Resources should be requested when the device is probed on the control bus rather then when the CODEC is bound to the sound card. This allows things like probe deferring and device managed allocations to work.

So move the GPIO request calls from the CODEC probe to the bus probe and also make them managed along the way.

The patch

ASoC: uda1380: Remove unused DAI ID defines

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.

Thanks, Mark

From: Lars-Peter Clausen lars@metafoo.de Date: Wed, 23 Nov 2016 10:30:10 +0100 Subject: [PATCH] ASoC: uda1380: Remove unused DAI ID defines

The DAI ID defines are back from the time when DAIs were referenced by a numerical ID. These days a string is used for matching instead and the defines are unused. The last user of these defines was removed in commit f0fba2ad1b6b ("ASoC: multi-component - ASoC Multi-Component Support"). So remove the defines as well.
