Subject[PATCH] [v2] ASoC: codecs: Fix runtime PM imbalance in tas2552_probe
Date
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.

Signed-off-by: Dinghao Liu <dinghao.liu@zju.edu.cn>

Changelog:

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