From: Zhang Qilong <zhangqilong3@huawei.com> [ Upstream commit b9a0da5b2edcae2a901b85c8cc42efc5bec4bd7b ] 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_adfsdm_probe.
