gpios control protocol with PL2303 RA, so I only
test it with PL2303 RA and HXA, I don't have HXD,
but because it is *office* HXD gpio

Always? Are you sure? It's probably better to write might have as they
are unlikely to be accessible even if the pins exist
Hi Johan Hovold.

This isn't the right place for this abstraction. Most of the setup code
sysfs interface, etc),
then call pl2303_release(unplug usb-serial convertor, modprobe -r, etc),
will cause trouble, so we need to make sure there is no gpio user before
call pl2303_release.

Ok, before I send out next version, I still has some
