Only tpm_tis and tpm_tis_synquacer have a dedicated way to access
multiple bytes at once, every other driver will just fall back to
read_bytes/write_bytes. Therefore, remove the read16/read32/write32
calls and move their logic to read_bytes/write_bytes.

Returning an error value in an i2c remove callback results in a generic
error message being emitted by the i2c core, but otherwise it doesn't make
a difference. The device goes away anyhow and the devm cleanups are
called.
So instead of triggering the generic i2c error message, emit a more helpful
message if a problem occurs and return 0 to suppress the generic message.
This patch is a preparation for making i2c remove callbacks return void.

ASoC: Updates for v5.19
This is quite a big update, partly due to the addition of some larger
drivers (more of which is to follow since at least the AVS driver is
still a work in progress) and partly due to Charles' work sorting out
our handling of endianness. As has been the case recently it's much
more about drivers than the core.
- Overhaul of endianness specification for data formats, avoiding
needless restrictions due to CODECs.
- Initial stages of Intel AVS driver merge.
- Introduction of v4 IPC mechanism for SOF.
- TDM mode support for AK4613.
- Support for Analog Devices ADAU1361, Cirrus Logic CS35L45, Maxim
MAX98396, MediaTek MT8186, NXP i.MX8 micfil and SAI interfaces,
nVidia Tegra186 ASRC, and Texas Instruments TAS2764 and TAS2780

It will cause null-ptr-deref when using 'res', if platform_get_resource()
returns NULL, so move using 'res' after devm_ioremap_resource() that
will check it to avoid null-ptr-deref.
And use devm_platform_get_and_ioremap_resource() to simplify code.

Looks like almost all changes to this driver had been tree-wide
refactoring since git era begun. There is one commit from Al
15 years ago which could potentially be fixing a real bug.
The driver is using virt_to_bus() and is a real magnet for pointless
cleanups. It seems unlikely to have real users. Let's try to shed
this maintenance burden.

Update the VCAP filters to support multiple tag_8021q CPU ports.
TX works using a filter for VLAN ID on the ingress of the CPU port, with
a redirect and a VLAN pop action. This can be updated trivially by
amending the ingress port mask of this rule to match on all tag_8021q
CPU ports.
RX works using a filter for ingress port on the egress of the CPU port,
with a VLAN push action. Here we need to replicate these filters for
each tag_8021q CPU port, and let them all have the same action.
This means that the OCELOT_VCAP_ES0_TAG_8021Q_RXVLAN() cookie needs to
encode a unique value for every {user port, CPU port} pair it's given.
Do this by encoding the CPU port in the upper 16 bits of the cookie, and
the user port in the lower 16 bits.

There is a desire for the felix driver to gain support for multiple
tag_8021q CPU ports, but the current model prevents it.
This is because ocelot_apply_bridge_fwd_mask() only takes into
consideration whether a port is a tag_8021q CPU port, but not whose CPU
port it is.
We need a model where we can have a direct affinity between an ocelot
port and a tag_8021q CPU port. This serves as the basis for multiple CPU
ports.
Declare a "dsa_8021q_cpu" backpointer in struct ocelot_port which
encodes that affinity. Repurpose the "ocelot_set_dsa_8021q_cpu" API to
"ocelot_assign_dsa_8021q_cpu" to express the change of paradigm.
Note that this change makes the first practical use of the new
ocelot_port->index field in ocelot_port_unassign_dsa_8021q_cpu(), where
we need to remove the old tag_8021q CPU port from the reserved VLAN range.

tag_8021q CPU
Add more logic to ocelot_port_{,un}set_dsa_8021q_cpu() from the ocelot
switch lib by encapsulating the ocelot_apply_bridge_fwd_mask() call that
felix used to have.
This is necessary because the CPU port change procedure will also need
to do this, and it's good to reduce code duplication by having an entry
point in the ocelot switch lib that does all that is needed.

PGID_CPU must be updated every time a port is configured or unconfigured
as a tag_8021q CPU port. The ocelot switch lib already has a hook for
that operation, so move the updating of PGID_CPU to those hooks.
These bits are pretty specific to DSA, so normally I would keep them out
of the common switch lib, but when tag_8021q is in use, this has
implications upon the forwarding mask determined by
ocelot_apply_bridge_fwd_mask() and called extensively by the switch lib.

PGID_BC is configured statically by ocelot_init() to flood towards the
CPU port module, and dynamically by ocelot_port_set_bcast_flood()
towards all user ports.
When the tagging protocol changes, the intention is to turn off flooding
towards the old pipe towards the host, and to turn it on towards the new
pipe.
Due to a recent change which removed the adjustment of PGID_BC from
felix_set_host_flood(), 3 things happen.
- when we change from NPI to tag_8021q mode: in this mode, the CPU port
module is accessed via registers, and used to read PTP packets with
timestamps. We fail to disable broadcast flooding towards the CPU port
module, and to enable broadcast flooding towards the physical port
that serves as a DSA tag_8021q CPU port.
- from tag_8021q to NPI mode: in this mode, the CPU port module is
redirected to a physical port. We fail to disable broadcast flooding
towards the physical tag_8021q CPU port, and to enable it towards the
CPU port module at ocelot->num_phys_ports.
- when the ports are put in promiscuous mode, we also fail to update
PGID_BC towards the host pipe of the current protocol.
First issue means that felix_check_xtr_pkt() has to do extra work,
because it will not see only PTP packets, but also broadcasts. It needs
to dequeue these packets just to drop them.
Third issue is inconsequential, since PGID_BC is allocated from the
nonreserved multicast PGID space, and these PGIDs are conveniently
initialized to 0x7f (i.e. flood towards all ports except the CPU port
module). Broadcasts reach the NPI port via ocelot_init(), and reach the
tag_8021q CPU port via the hardware defaults.
Second issue is also inconsequential, because we fail both at disabling
and at enabling broadcast flooding on a port, so the defaults mentioned
above are preserved, and they are fine except for the performance impact.

The VBT send packet port selection was never updated for ICL+ where the
2nd link is on port B instead of port C as in VLV+ DSI.
First, single link DSI needs to use the configured port instead of
relying on the VBT sequence block port. Remove the hard-coded port C
check here and make it generic. For reference, see commit f915084edc5a
("drm/i915: Changes related to the sequence port no for") for the
original VLV specific fix.
Second, the sequence block port number is either 0 or 1, where 1
indicates the 2nd link. Remove the hard-coded port C here for 2nd
link. (This could be a "find second set bit" on DSI ports, but just
check the two possible options.)
Third, sanity check the result with a warning to avoid a NULL pointer
dereference.

In normal stop process, it does like this:
do_md_stop
|
__md_stop (pers->free(); mddev->private=NULL)
|
md_free (free mddev)
__md_stop sets mddev->private to NULL after pers->free. The raid device
will be stopped and mddev memory is free. But in reshape, it doesn't
free the mddev and mddev will still be used in new raid.
In reshape, it first sets mddev->private to new_pers and then runs
old_pers->free(). Now raid0 sets mddev->private to NULL in raid0_free.
The new raid can't work anymore. It will panic when dereference
mddev->private because of NULL pointer dereference.
It can panic like this:

Unregister sync_thread doesn't need to hold reconfig_mutex since it
doesn't reconfigure array.
And it could cause deadlock problem for raid5 as follows:
1. process A tried to reap sync thread with reconfig_mutex held after echo
idle to sync_action.
2. raid5 sync thread was blocked if there were too many active stripes.
3. SB_CHANGE_PENDING was set (because of write IO comes from upper layer)
which causes the number of active stripes can't be decreased.
4. SB_CHANGE_PENDING can't be cleared since md_check_recovery was not able
to hold reconfig_mutex.

GCC 12 currently generates a rather inconsistent warning:
drivers/net/ethernet/broadcom/tg3.c:17795:51: warning: array subscript 5 is above array bounds of ‘struct tg3_napi[5]’ [-Warray-bounds]
17795 | struct tg3_napi *tnapi = &tp->napi[i];
| ~~~~~~~~^~~
i is guaranteed < tp->irq_max which in turn is either 1 or 5.
There are more loops like this one in the driver, but strangely
GCC 12 dislikes only this single one.
Silence this silliness for now.

GCC 12 gets upset because driver allocates partial
struct ice_aqc_sw_rules_elem buffers. The writes are
within bounds.
Silence these warnings for now, our build bot runs GCC 12
so we won't allow any new instances.
