pxa_camera init() callback is sometimes abused to setup MFP for PXA CIF, or even to request GPIOs to be used by the camera *sensor*. These initializations can be performed statically in machine init functions. The current semantics for this init() callback is ambiguous anyways, it is invoked in pxa_camera_activate(), hence at device node open, but its users use it like a generic initialization to be done at module init time (configure MFP, request GPIOs for *sensor* control).
