In link_set_dsc_pps_packet(), 'struct display_stream_compressor *dsc'
was dereferenced in a DC_LOGGER_INIT(dsc->ctx->logger); before the 'dsc'
NULL pointer check.
Fixes the below:

====================
Netfilter fixes for net
The following batch contains Netfilter fixes for net. Slightly larger
than usual because this batch includes several patches to tighten the
nf_tables control plane to reject inconsistent configuration:
1) Restrict NFTA_SET_POLICY to NFT_SET_POL_PERFORMANCE and
NFT_SET_POL_MEMORY.
2) Bail out if a nf_tables expression registers more than 16 netlink
attributes which is what struct nft_expr_info allows.
3) Bail out if NFT_EXPR_STATEFUL provides no .clone interface, remove
existing fallback to memcpy() when cloning which might accidentally
duplicate memory reference to the same object.
4) Fix br_netfilter interaction with neighbour layer. This requires
three preparation patches:
- Use nf_bridge_get_physinif() in nfnetlink_log
- Use nf_bridge_info_exists() to check in br_netfilter context
is available in nf_queue.
- Pass net to nf_bridge_get_physindev()
And finally, the fix which replaces physindev with physinif
in nf_bridge_info.
Patches from Pavel Tikhomirov.
5) Catch-all deactivation happens in the transaction, hence this
oneliner to check for the next generation. This bug uncovered after
the removal of the _BUSY bit, which happened in set elements back in
summer 2023.
6) Ensure set (total) key length size and concat field length description
is consistent, otherwise bail out.
7) Skip set element with the _DEAD flag on from the netlink dump path.
A tests occasionally shows that dump is mismatching because GC might
lose race to get rid of this element while a netlink dump is in
progress.
8) Reject NFT_SET_CONCAT for field_count < 1.
9) Use IP6_INC_STATS in ipvs to fix preemption BUG splat, patch
from Fedor Pchelkin.

strlcpy() reads the entire source buffer first. This read may exceed
the destination size limit. This is both inefficient and can lead
to linear read overflows if a source string is not NUL-terminated[1].
Additionally, it returns the size of the source string, not the
resulting size of the destination string. In an effort to remove strlcpy()
completely[2], replace strlcpy() here with strscpy().
Nothing checks the return value here, so a direct replacement with
strspy() is possible.

The stm32mp25 has only a single interrupt line used for both
events and errors. In order to cope with that, reorganise the
error handling code so that it can be called either from the
common handler (used in case of SoC having only a single IT line)
and the error handler for others.
The CR1 register also embeds a new FMP bit, necessary when running
at Fast Mode Plus frequency. This bit should be used instead of
the SYSCFG bit used on other platforms.
Add a new compatible to distinguish between the SoCs and two
boolean within the setup structure in order to know if the
platform has a single/multiple IT lines and if the FMP bit
within CR1 is available or not.

The irq handling is currently split between the irq handler
and the threaded irq handler. Some of the handling (such as
dma related stuffs) done within the irq handler might sleep or
take some time leading to issues if the kernel is built with
realtime constraints. In order to fix that, perform an overall
rework to perform most of the job within the threaded handler
and only keep fifo access in the non threaded handler.

I originally restricted i2c_register_spd() to only support systems
with up to 4 memory slots, so that we can experiment with it on
a limited numbers of systems. It's been more than 3 years and it
seems to work just fine, so the time has come to lift this arbitrary
limitation.
The maximum number of memory slots which can be connected to a single
I2C segment is 8, so support that many SPD EEPROMs. Any system with
more than 8 memory slots would have either multiple SMBus channels
or SMBus multiplexing, so it would need dedicated care. We'll get to
that later as needed.

To properly handle ACK on the bus when transferring more than one
message in polling mode, move the polling handling loop from
s3c24xx_i2c_message_start() to s3c24xx_i2c_doxfer(). This way
i2c_s3c_irq_nextbyte() is always executed till the end, properly
acknowledging the IRQ bits and no recursive calls to
i2c_s3c_irq_nextbyte() are made.
While touching this, also fix finishing transfers in polling mode by
using common code path and always waiting for the bus to become idle
and disabled.

There are reports of kernels crashing due to stack overflow while
running OpenShift (Kubernetes). The primary contributor to the stack
usage seems to be openvswitch, which is used by OVN-Kubernetes (based on
OVN (Open Virtual Network)), but NFS also contributes in some stack
traces.
There may be some opportunities to reduce stack usage in the openvswitch
code, but doing so potentially require tradeoffs vs performance, and
also requires testing across architectures.
Looking at stack usage across the kernel (using -fstack-usage), shows
that ppc64le stack frames are on average 50-100% larger than the
equivalent function built for x86-64. Which is not surprising given the
minimum stack frame size is 32 bytes on ppc64le vs 16 bytes on x86-64.
So increase the default stack size to 32KB for the modern 64-bit Book3S
platforms, ie. pseries (virtualised) and powernv (bare metal). That
leaves the older systems like G5s, and the AmigaOne (pasemi) with a 16KB
stack which should be sufficient on those machines.

Pull staging driver updates from Greg KH:
"Here is the "big" set of staging driver changes for 6.8-rc1. It's not
really that big this release cycle, not much happened except for 186
patches of coding style cleanups. The majority was in the rtl8192e
driver, but there are other smaller changes in a few other staging
drivers, full details in the shortlog.
All of these have been in linux-next for a while with no reported
issues"
