From: Ville Syrjälä <[email protected]>
Since commit 1455cf8dbfd0 ("driver core: emit uevents when
device is bound to a driver") the kernel started emitting
"bind" and "unbind" uevents which confuse the hid2hci
udev rules.
The symptoms on an affected machine (Dell E5400 in my case)
include bluetooth devices not appearing and udev hogging
the cpu as it's busy processing a constant stream of these
"bind"+"unbind" uevents.
Change the udev rules not do anything except for "add" and
"change" events. This seems to cure my machine at least.
v2: Don't mess up "change" (Zbyszek)
Fix up the commit message a bit

Reposting with BlueZ in subject and sob stripped. Maybe that helps in
getting a oneliner merged?
