Add a PM runtime increment to balance refcount. Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next 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

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.
