LC898217XC is a 11 bit DAC, designed for linear control
of voice coil motor. This driver creates a V4L2 subdevice
and provides control to set the desired focus.
Tested on Oneplus 6 (oneplus-enchilada)

Do you not want to restore the current position after resuming power?
Potentially use __v4l2_ctrl_handler_setup() to reset all controls
should any extra ones get added.

subscribe and unsubscribe_event hooks shouldn't be needed if it's only
for controls since e7724e23196a ("media: v4l2-subdev: Refactor
events"). That may not have been merged when you added this in v2.
