PCI Hotplug: Fix small mem leak in IBM Hot Plug Controller Driver
PCI Hotplug: Fix small mem leak in IBM Hot Plug Controller Driver

In drivers/pci/hotplug/ibmphp_ebda.c::ebda_rsrc_controller(), storage is
allocated with kzalloc() and assigned to 'tmp_slot'.  Then lots of
stuff, like ->flag, ->supported_speed etc is set in tmp_slot.  A bit
further down there's then this test :

  if (!bus_info_ptr1) {
    rc = -ENODEV;
    goto error;
  }

At this point, tmp_slot has not been assigned to anything, so when
erroring-out we want to free it, but nothing at the 'error:' label
free's 'tmp_slot' - and we can't really free 'tmp_slot' at 'error:'
since we may jump to that label later when 'tmp_slot' *has* been used
and we do not want it freed. So, the only sane option left seems to be
to kfree(tmp_slot) just before jumping to the 'error:' label in the one
place where this is what actually makes sense. The following patch does
just that and thus kills off a tiny potential memory leak.
