Yes it does, thank you. We do want to allow our customers to use the
go7007 driver with our products on older kernels, so I would like to
keep the v4l2-i2c-drv.h for now. I've addressed your other comments in
the revised patch:
From: Pete Eberlein <p...@sensoray.com>
This is a subdev conversion of the go7007 wis-sony-tuner i2c driver,
and places it with the other tuner drivers. This obsoletes the
wis-sony-tuner driver in the go7007 staging directory.
Priority: normal
