The kernel broke ABI, usually event%d was a child device of input%d,
e.g. like this

 /sys/class/input0/event0/

but with the conversion of input to struct device, it's now

 /sys/class/input0
 /sys/class/event0

and that freaks out HAL. So I guess that's why. Kay says that there's a
patch for this somewhere and that another option is just to use avoid
using CONFIG_SYSFS_DEPRECATED=y. Kay?
