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 <pete@xxxxxxxxxxxx>

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
