Hi,

Thanks for submitting this. I have just a couple of questions...

inputattach is generally silent when everything goes well. I can see how this
kind of info would be useful though; would you mind simply commenting the
printf() lines out, and I'll add a verbose mode later on?

Sure, I'll put it under #ifdef 0.

As above.

+#endif

Is this intentional? If so, could you mention it in the commit message?

Yes, it is intentional. I noticed that the SERIO_HAMPSHIRE support
is also missing from inputattach. I don't currently know if the
Hampshire touchscreen needs an init function or not, so it is a
placeholder at the moment. Also, the SERIO_HAMPSHIRE value is
smaller than SERIO_PS2MULT which is unconditionally enabled,
so maybe it doesn't need the #ifdef SERIO_HAMPSHIRE ... #endif
cover at all. I will mention it in the commit message for the v2 patch,
which I will send tomorrow.

Best regards,
Zoltán Böszörményi
