From my understanding the STAC_HP_DV5 only exists to enable gpio0 by default, 
while STAC_HP_M4 will besides enabling it (passing the "if (spec->board_config 
> STAC_92HD71BXX_REF)" check), will also do extra setup. I don't know if 
enabling gpio0 with dir=1 by default will introduce some bug with some 
machine, but the idea is that all HP laptops with these codecs looks to need 
gpio0 enabled; even if some of them needs hp-m4 because of extra setup needed 
(besides gpio initialization), hp-dv5 would be safe for them as both enable 
gpio the same way. But I agree we should take care in case initializing gpio0 
by default can introduce bugs with another unlisted hp laptops.
