Since we cannot make sure that the 'hook_mask' will always be none
zero here. If it equals to zero, the num_hooks will be zero too,
and then kmalloc() will return ZERO_SIZE_PTR, which is (void *)16.
Then the following error check will fails:
ops = kmalloc(sizeof(*ops) * num_hooks, GFP_KERNEL);
if (ops == NULL)
return ERR_PTR(-ENOMEM);
So this patch will fix this with just doing the zero check before
kmalloc() is called.
Maybe the case above will never happen here, but in theory.

Before commit 6d7b857d54 ("net: use lib/percpu_counter API for
fragmentation mem accounting"), setting the reassembly high threshold
to 0 prevented fragment reassembly as first fragment would be always
evicted before second could be added to the queue. While inefficient,
some users apparently relied on this method.
Since the commit mentioned above, a percpu counter is used for
reassembly memory accounting and high batch size avoids taking slow path
in most common scenarios. As a result, a whole full sized packet can be
reassembled without the percpu counter's main counter changing its value
so that even with high_thresh set to 0, fragmented packets can be still
reassembled and processed.
Add explicit check preventing reassembly if high threshold is zero.

This series adds HNS support of acpi. The routine will call some ACPI
helper functions, like acpi_dev_found() and acpi_evaluate_dsm(), which
are not included in other cases. In order to make system compile
successfully in other cases except ACPI, it needs to add relative stub
functions to linux/acpi.h. And we use device property functions instead
of serial helper functions to suport both DT and ACPI cases. And then
add the supports of ACPI for HNS.

New DSA bind, switches as devices
The interesting patches here are the last three. They implement a new
binding for DSA, which removes a few limitations of the current DSA
binding. In particular, it allows switches to be true Linux devices.
These devices can be on any type of bus, unlike the old DSA binding
which assumes MDIO. See the commit log for more details. The second to
last patch modifies an existing boards device tree to use the new
binding, giving a good example of how switches can be true MDIO

The chip data structure is used while parsing the whole old binding,

this is reversed, the switches exist first, and the interconnections
between the switches is derived from the individual switch

The platform data nr_chips is used when validating a received packet,
to ensure it comes from a know switch chip. The number of possible
switches is limited to DSA_MAX_SWITCHES, so use this as the first
validation step. The new binding allows holes in the dst->ds[] array,
so also ensure ensure there is a valid dsa_switch for this packet.

The DSA layer should no longer assume the switch is connected to an
MDIO bus. As a result, we cannot use the address on the MDIO bus when
forming the name of the switches internal MDIO bus for its builtin and
possibly external PHYs. The switch index is sufficient to make the
name unique, so drop the MDIO address.

The new binding does not make use of dsa_chip_data, a.k.a cd. When
retrieving the size of the EEPROM attached to a switch, don't assume
there is a cd attached to the switch structure.

Commit a91eb52abb ("qed: Revisit chain implementation") contains an
incorrect implementation for BE platforms, as device's regpairs containing
addresses are LE and they're not converted correctly when read back.
In addition, it raises a compilation warning for 32-bit platforms where
dma_addr_t is a 32-bit variable.
