Subject: [PATCH 25/25] HID: multitouch: make MT_CLS_ALWAYS_TRUE the new default class
By running a test on all the traces of the devices I have,
I noticed that the class MT_CLS_ALWAYS_TRUE could handle all
the devices I've seen so far without any other quirks.
I guess this is the behavior Win 7 requires in its driver.
We can change the default class then and keep the existing classes
for backward compatibility and performances for some of them.
Two operations have been done:
- replaced MT_CLS_DEFAULT by MT_CLS_NSMU
- then replaced MT_CLS_ALWAYS_TRUE by MT_CLS_DEFAULT
