After further testing reverting the following commit does in fact
resolve the bug:

commit b1a1442a23776756b254b69786848a94d92445ba
Author: Jiri Kosina [off-list ref]

    HID: core: fix reporting of raw events

Reverting this commit in v3.12-rc2 prevents the system from locking up, 
which happens when connecting a bluetooth trackpad.

Jiri, do you think we should revert this patch, or is there some further 
debugging/data collecting you would like to do?

Hi Joseph,

in this mail:

	Message-ID: [ref]

you said that reverting this commit doesn't prevent the lockups, so I am 
rather confused ... ?

Thanks,

The testing was invalid.  Reverting commit b1a1442 does resolve the bug
and stop the lockups.

It looks like magicmouse_raw_event() returns 1 on success and 0 on
failure.
