The out_msi_disable label should be before cleanup_nomem to additionally
benefit from the call to iounmap. Subsequent gotos are adjusted to go to
out_msi_disable instead of cleanup_nomem, which now follows it. This is
safe because pci_disable_msi does nothing if pci_enable_msi was not called.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

There's a code path in pmcraid that can be reached via device ioctl that
causes all sorts of ugliness, including heap corruption or triggering the
OOM killer due to consecutive allocation of large numbers of pages.
First, the user can call pmcraid_chr_ioctl(), with a type
PMCRAID_PASSTHROUGH_IOCTL. This calls through to
pmcraid_ioctl_passthrough(). Next, a pmcraid_passthrough_ioctl_buffer
is copied in, and the request_size variable is set to
buffer->ioarcb.data_transfer_length, which is an arbitrary 32-bit
signed value provided by the user. If a negative value is provided
here, bad things can happen. For example,
pmcraid_build_passthrough_ioadls() is called with this request_size,
which immediately calls pmcraid_alloc_sglist() with a negative size.
The resulting math on allocating a scatter list can result in an
overflow in the kzalloc() call (if num_elem is 0, the sglist will be
smaller than expected), or if num_elem is unexpectedly large the
subsequent loop will call alloc_pages() repeatedly, a high number of
pages will be allocated and the OOM killer might be invoked.
It looks like preventing this value from being negative in
pmcraid_ioctl_passthrough() would be sufficient.

Currently, bnx2fc has a hba structure that can work with only a single vlan
interface. When there is a change in vlan id, it does not have the capability
to switch to different vlan interface. To solve this problem, a new structure
called 'interface' has been introduced, and each hba can now have multiple
interfaces, one per vlan id.
Most of the patch is a moving the interface specific fields from hba to the
interface structure, and appropriately modifying the dereferences. A list of
interfaces (if_list) is maintained along with adapter list. During a create
call, the interface structure is allocated and added to if_list and deleted &
freed on a destroy call. Link events are propagated to all interfaces
belonging to the hba.
