From: Zhang Qilong <zhangqilong3@huawei.com>
[ Upstream commit 93618e5e05a3ce4aa6750268c5025bdb4cb7dc6e ]
The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by moving pm_runtime_enable to the endding of stm32_i2s_probe.
Fixes:32a956a1fadf ("ASoC: stm32: i2s: add pm_runtime support")
