Fortunately those are false-positives:

# modprobe i915
# echo scan > /debug/kmemleak
# cat /debug/kmemleak
(lots of "leaks")
# rmmod i915
# echo scan > /debug/kmemleak
# cat /debug/kmemleak
(no leaks)
All the memory allocated when loading the module is
freed in trace_module_remove_events() at module unload.

But I haven't looked into how to suppress those false-postives.
I'd like to, but I'm going to leave my office and won't be
back until 26th..
