[PATCH 1/2] HID: multitouch: rename MT_CLS_EGALAX_P80H84 to MT_CLS_EGALAX_WIN8

[buingoc67]

From: hmtheboy154 <buingoc67@gmail.com>

The Dell Pro Rugged 12 Tablet RA02260 uses an i2c touchscreen from
eGalax that exposes the same HID_GROUP_MULTITOUCH_WIN_8 as the
P80H84 and also requires the same quirks to make multitouch work.

Rename the class to MT_CLS_EGALAX_WIN8 for more general use.

Thanks a lot for the patches.

I know that the kernel documentation is now a little bit more liberal 
about not having to use real names, but "well established identities" 
being fine, but stil ... would you mind submitting this under some more 
comprehensible authorship? (anonymous submissions are still not allowed, 
BTW).

hmtheboy154 / buingoc67 doesn't really sound too well established identity 
to me, unfortunately :)

Thanks,

Hi, I don't understand why it take my email "buingoc67" instead 
of the git user.name that I set as "hmtheboy154". Is there any way 
that I can change this ? Or else I'll submit the changes under my 
org email (hmtheboy154@blisslabs.org) if that's ok.
