2023-09-27media: i2c: ov8856: Drop system suspend and resume handlersLaurent Pinchart
Stopping streaming on a camera pipeline at system suspend time, and restarting it at system resume time, requires coordinated action between the bridge driver and the camera sensor driver. This is handled by the bridge driver calling the sensor's .s_stream() handler at system suspend and resume time. There is thus no need for the sensor to independently implement system sleep PM operations. Drop them. The streaming field of the driver's private structure is now unused, drop it as well.
