In the cases where adev->jpeg.num_jpeg_inst is zero or the condition adev->jpeg.harvest_config & (1 << i) is always non-zero the variable ret is never set to an error condition and the function returns an uninitialized value in ret. Since the only exit condition at the end if the function is a success then explicitly return 0 rather than a potentially uninitialized value in ret.
We should actually never hit this condition in practice because the driver won't initialize this module if all of the instances are harvested, but better safe than sorry. Applied.
Thanks,
Alex
