[1/1] ASoC: ti: omap-mcbsp: Fix runtime PM underflow warnings commit: fbb74e56378d8306f214658e3d525a8b3f000c5a 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

We need to check for an active device as otherwise we get warnings for some mcbsp instances for "Runtime PM usage count underflow!".
