In pwc_video_open() the camera is sent a poweron command only if the
global power_save is set. It is possible to have a camera in the powered
off state but also have power_save be zero, for example if the module
has been reinstalled with power_save=0 after powering off the camera.
In any case, a belt-and-braces approach would be to always send the
poweron command.
Diff attached.
