Subject: Re: [PATCH] Input: psmouse - cleanup Focaltech code

Other drivers, like Synaptics use the same as I suggested. They even
shorten in psmouse-base.c psmouse_protocol.name to SynPS/2.
You used FocaltechPS/2. I think it is OK.

I do not think it is a big problem of changing the naming. It happens a lot.

I still have the hardware and I am still thankful to you that you
wrote that driver.

Now I am trying to write my own for a new i2c touchpad that is used in
new Asus laptops ;-)
