If you have a pointer to hv_driver, why do you need a full 'struct
device_driver' here? That sounds really wrong.
Actually, having 'struct device_driver' within a structure called
"driver_context" seems wrong, this should be what 'struct hv_driver'
really is, right?
So no, I can't take this patch, as it isn't solving the root problem
here.
