The driver stores a frame interval value supposed to be in line with hardware state in a device private structure. Since the driver initial submission, the respective field of the structure has never been initialised on device probe. Moreover, if updated from .s_frame_interval(), a new value is stored before it is applied on hardware. If an error occurs during device update, the stored value may no longer reflect hardware state and consecutive calls to .g_frame_interval() may return incorrect information. Assuming a failed update of the device means its actual state hasn't changed, update the frame interval field of the device private structure with a new value only after it is successfully applied on hardware so it always reflects actual hardware state to the extent possible. Also, initialise the field with hardware default frame interval on device probe.
