[alsa-devel] [PATCH] ASoC: fsl_sai: Fix exiting path on probing failure
If the imx-sdma driver is built as a module, the fsl-sai device doesn't disable on probing failure, which causes the warning in the next probing:
================================================================== fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable! fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable! fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable! fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable! fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable! fsl-sai 308a0000.sai: Unbalanced pm_runtime_enable! ==================================================================
Disabling the device properly fixes the issue.

The patch
ASoC: fsl_sai: Fix exiting path on probing failure
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6
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
