From: Zhang Qilong <zhangqilong3@huawei.com> [ Upstream commit b73f11e895e140537e7f8c7251211ccd3ce0782b ] 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 mt6660_i2c_probe.
