There is a rumtime PM imbalance between the error handling path
after devm_snd_soc_register_component() and all other error
handling paths. Add a PM runtime increment to balance refcount.

Changelog:
v2: - Add a PM runtime increment to fix it instead of moving
the PM related operations after the registration.

Thanks!
[1/1] ASoC: codecs: Fix runtime PM imbalance in tas2552_probe
commit: 7b3f5b207da5116add56c335c5fb92cee140dc63
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
