Commit Message

a) Add missing pm_runtime_disable() when probe error out. It could
avoid pm_runtime implementation complains when removing and probing
again the driver.
b) Add remove for missing pm_runtime_disable().

Fix:c590fa80b3928 ("ASoC: fsl_xcvr: register platform component before registering cpu dai")
Signed-off-by: Zhang Qilong <zhangqilong3@huawei.com>
---
v2:
- Add remove to put PM usage counter.

v3:
- Modify the commit message.

Thanks!

[1/1] ASoC: fsl_xcvr:Fix unbalanced pm_runtime_enable in fsl_xcvr_probe
      commit: 9c3148dec7d2d40ef727b8789d3e9410ad6d4a1f

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
