For some reason rt5670_i2c_probe() does a pm_runtime_put() at the end of a successful probe. But it has never done a pm_runtime_get() leading to the following error being logged into dmesg: rt5670 i2c-10EC5640:00: Runtime PM usage count underflow! Fix this by removing the unnecessary pm_runtime_put().
