In ofdpa_port_fdb(), the hash_del() only unlinks the node from
hash table, but does not free it.

Fix this by adding kfree(found) after the !found == removing check,
where the pointer value is no longer needed.

Found by Coccinelle kfree script.

... and PCI device helpers.

The various struct pci_device_id arrays were initialized mostly by one
the PCI_DEVICE macros and then list expressions. The latter isn't easily
readable if you're not into PCI. Using named initializers is more
explicit and thus easier to parse.

Also use PCI_DEVICE* helper macros to assign .vendor, .device,
.subvendor and .subdevice where appropriate and skip explicit
assignments of 0 (which the compiler takes care of).

The secret plan is to make struct pci_device_id::driver_data an
anonymous union (similar to
https://lore.kernel.org/all/cover.1776579304.git.u.kleine-koenig@baylibre.com/)
and that requires named initializers. But it's also a nice cleanup on
its own.

This change doesn't introduce changes to the compiled pci_device_id
arrays. Tested on x86 and arm64.

Combining the allocations simplifies things, especially the free path.

Remove ofdpa_group_tbl_entry_free as a result. kfree is shorter.

Add __counted_by for extra runtime analysis.

This converts some of the visually simpler cases that have been split
over multiple lines.  I only did the ones that are easy to verify the
resulting diff by having just that final GFP_KERNEL argument on the next
line.

Somebody should probably do a proper coccinelle script for this, but for
me the trivial script actually resulted in an assertion failure in the
middle of the script.  I probably had made it a bit _too_ trivial.

So after fighting that far a while I decided to just do some of the
syntactically simpler cases with variations of the previous 'sed'
scripts.

The more syntactically complex multi-line cases would mostly really want
whitespace cleanup anyway.

This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

In rocker_world_port_pre_init(), rocker_port->wpriv is allocated with
kzalloc(wops->port_priv_size, GFP_KERNEL). However, in
rocker_world_port_post_fini(), the memory is only freed when
wops->port_post_fini callback is set:

    if (!wops->port_post_fini)
        return;
    wops->port_post_fini(rocker_port);
    kfree(rocker_port->wpriv);

Since rocker_ofdpa_ops does not implement port_post_fini callback
(it is NULL), the wpriv memory allocated for each port is never freed
when ports are removed. This leads to a memory leak of
sizeof(struct ofdpa_port) bytes per port on every device removal.

Fix this by always calling kfree(rocker_port->wpriv) regardless of
whether the port_post_fini callback exists.
