Every time the driver is reloaded, the warning message
Unbalanced pm_runtime_enable! is triggered due to unbalanced
power.disable_depth. This is because pm_runtime_enable() is called
during driver probe but pm_runtime_disable() is missed on driver remove.
This also restores the device's runtime
On driver removal, pm_runtime_get_sync() is called, but
pm_runtime_put_sync() is missed. So once the driver is reloaded, the
device's power.usage_count is unbalanced and the idle callback for the
device will never be called.
