SubjectPossible memory leak in ata_piix.c
Hi,

Kmemleak found a possible memory leak in piix_init_one() in
drivers/ata/ata_piix.c. This only appeared after 2.6.19, maybe caused
by the recent patches to this area. Kmemleak cannot find any track of
the kzalloc'ed piix_host_priv structure allocated in the above
function and reports it. The allocation stack trace is below:

unreferenced object 0xde9bca60 (size 4):
  [<c018d85d>] __kmalloc_track_caller
  [<c0179249>] __kzalloc
  [<c02cf33f>] piix_init_one
  [<c023dc2d>] pci_call_probe
  [<c023dc81>] __pci_device_probe
  [<c023dcb9>] pci_device_probe
  [<c029b5fc>] really_probe
  [<c029b728>] driver_probe_device
  [<c029b8c1>] __driver_attach
  [<c029a879>] bus_for_each_dev
  [<c029b8e9>] driver_attach
  [<c029ae9c>] bus_add_driver
  [<c029bd27>] driver_register
  [<c023e035>] __pci_register_driver
  [<c02cf4ef>] piix_init

Thanks.
