Subject: linux-3.7.[1,4]: kmemleak in i801_probe

Hi,
  I already reported this to lkml recently with linux-3.7.1 but this is to let you know
that with 3.7.4 I am still getting this kmemleak reported by the kernel.

unreferenced object 0xffff88040b614690 (size 256):
  comm "swapper/0", pid 1, jiffies 4294937573 (age 133834.550s)
