The generic detection of hid-mt devices has two major flaws, and was
merged prematurely. Firstly, the hid-multitouch gets loaded even when
the device is handled by a special device. Secondly, the patch only
partially duplicates the device whitelist already present in hid-core,
effectively rendering a number of devices non-functional.

Hi Jiri,

Unfortunately, the recently discussed solution does not seem to work,
so there is only a revert for now.

I was planning to send a second patch, very small and concise, based
on Benjamins patch, but

1. It still does not resolve the
hid-multitouch-gets-loaded-for-every-hid-device problem, and

Hmm, I thought it should work. What is the catch?

In other words, there is currently no viable solution.

Thanks, I will be including the patch in my next pile of fixes for 3.2 
that will go to Linus.
