Subject: [PATCH] media: i2c: ov5647: fix power cleanup on remove
ov5647_remove() disables runtime PM without powering off the sensor if
it is still runtime active. pm_runtime_disable() does not invoke the
runtime suspend callback, so the sensor can remain powered on.
If the device is not already runtime suspended, call ov5647_power_off()
and mark the runtime PM state as suspended.
This issue was found by manual code inspection.
