9f8608fce9 io_uring/cmd: remove unused io_uring_cmd_iopoll_done()
io_uring_cmd_iopoll_done()'s only caller was removed in commit
9ce6c9875f ("nvme: always punt polled uring_cmd end_io work to
task_work"). So remove the unused function too.

dd386b0d5e io_uring/uring_cmd: correct io_uring_cmd_done() ret type
io_uring_cmd_done() takes the result code for the CQE as a ssize_t ret
argument. However, the CQE res field is a s32 value, as is the argument
to io_req_set_res(). To clarify that only s32 values can be faithfully
represented without truncation, change io_uring_cmd_done()'s ret
argument type to s32.

9be5c47908 dt-bindings: display/msm: expand to support MST
On a vast majority of Qualcomm chipsets DisplayPort controller can
support several MST streams (up to 4x). To support MST these chipsets
use up to 4 stream pixel clocks for the DisplayPort controller and
several extra register regions. Expand corresponding region and clock
bindings for these platforms and fix example schema files to follow
updated bindings.

Note: On chipsets that support MST, the number of streams supported
can vary between controllers. For example, SA8775P supports 4 MST
streams on mdss_dp0 but only 2 streams on mdss_dp1.

0253f5ef8d dt-bindings: display/msm: drop assigned-clock-parents for dp controller
DP controller schema documents assigned-clocks and
assigned-clock-parents. However these assignments should not be a part
of the ABI: there are no actual requirements on the order of the
assignments, MST cases require different number of clocks to be
assigned, etc.

Instead of fixing up the documentation, drop the assigned-clock-parents
and assigned-clocks from the bindings. The generic clock/clock.yaml
already covers these properties.

5484265fd6 dt-bindings: display/msm: dp-controller: fix fallback for SM6350
Currently SM6350 uses qcom,sm8350-dp as a fallback compatible entry.
This works, but adding DP MST support will reveal that this SoC is
not fully compatible with SM8350 platform: the former one doesn't
provide MST support, while the latter one will get it. DT schema for
SM8350 is going to demand MST-related clocks which SM6350 doesn't
provide.

Add new entry for SM6350 with fallback to SC7180 (which belongs to the
same generation and also doesn't have MST support). SC7180 has been
supported by the Linux kernel long ago (and long before SM8350 support
was added).

5d6b58c932 net: lockless sock_i_ino()
Followup of commit c51da3f7a1 ("net: remove sock_i_uid()")

A recent syzbot report was the trigger for this change.

Over the years, we had many problems caused by the
read_lock[_bh](&sk->sk_callback_lock) in sock_i_uid().

We could fix smc_diag_dump_proto() or make a more radical move:

Instead of waiting for new syzbot reports, cache the socket
inode number in sk->sk_ino, so that we no longer
need to acquire sk->sk_callback_lock in sock_i_ino().

This makes socket dumps faster (one less cache line miss,
and two atomic ops avoided).

Prior art:

commit 25a9c8a443 ("netlink: Add __sock_i_ino() for __netlink_diag_dump().")
commit 4f9bf2a2f5 ("tcp: Don't acquire inet_listen_hashbucket::lock with disabled BH.")

ede965fd55 i2c: rtl9300: remove broken SMBus Quick operation support
Remove the SMBus Quick operation from this driver because it is not
natively supported by the hardware and is wrongly implemented in the
driver.

The I2C controllers in Realtek RTL9300 and RTL9310 are SMBus-compliant
but there doesn't seem to be native support for the SMBus Quick
operation. It is not explicitly mentioned in the documentation but
looking at the registers which configure an SMBus transaction, one can
see that the data length cannot be set to 0. This suggests that the
hardware doesn't allow any SMBus message without data bytes (except for
those it does on it's own, see SMBus Block Read).

The current implementation of SMBus Quick operation passes a length of
0 (which is actually invalid). Before the fix of a bug in a previous
commit, this led to a read operation of 16 bytes from any register (the
one of a former transaction or any other value.

This caused issues like soft-bricked SFP modules after a simple probe
with i2cdetect which uses Quick by default. Running this with SFP
modules whose EEPROM isn't write-protected, some of the initial bytes
are overwritten because a 16-byte write operation is executed instead of
a Quick Write. (This temporarily soft-bricked one of my DAC cables.)

Because SMBus Quick operation is obviously not supported on these
controllers (because a length of 0 cannot be set, even when no register
address is set), remove that instead of claiming there is support. There
also shouldn't be any kind of emulated 'Quick' which just does another
kind of operation in the background. Otherwise, specific issues occur
in case of a 'Quick' Write which actually writes unknown data to an
unknown register.

06418cb5a1 i2c: rtl9300: ensure data length is within supported range
Add an explicit check for the xfer length to 'rtl9300_i2c_config_xfer'
to ensure the data length isn't within the supported range. In
particular a data length of 0 is not supported by the hardware and
causes unintended or destructive behaviour.

This limitation becomes obvious when looking at the register
documentation [1]. 4 bits are reserved for DATA_WIDTH and the value
of these 4 bits is used as N + 1, allowing a data length range of
1 <= len <= 16.

Affected by this is the SMBus Quick Operation which works with a data
length of 0. Passing 0 as the length causes an underflow of the value
due to:

(len - 1) & 0xf

and effectively specifying a transfer length of 16 via the registers.
This causes a 16-byte write operation instead of a Quick Write. For
example, on SFP modules without write-protected EEPROM this soft-bricks
them by overwriting some initial bytes.

For completeness, also add a quirk for the zero length.

Fix the current check for number of channels (child nodes in the device

if (device_get_child_node_count(dev) >= RTL9300_I2C_MUX_NCHAN)

RTL9300_I2C_MUX_NCHAN gives the maximum number of channels so checking
with '>=' isn't correct because it doesn't allow the last channel
number. Thus, fix it to:

b4ada0618e tools: ynl-gen: fix nested array counting
The blamed commit introduced the concept of split attribute
counting, and later allocating an array to hold them, however
TypeArrayNest wasn't updated to use the new counting variable.

Abbreviated example from tools/net/ynl/generated/nl80211-user.c:
nl80211_if_combination_attributes_parse(...):
  unsigned int n_limits = 0;
  [...]
  ynl_attr_for_each(attr, nlh, yarg->ys->family->hdr_len)
	if (type == NL80211_IFACE_COMB_LIMITS)
		ynl_attr_for_each_nested(attr2, attr)
			dst->_count.limits++;
  if (n_limits) {
	dst->_count.limits = n_limits;
	/* allocate and parse attributes */
  }

In the above example n_limits is guaranteed to always be 0,
hence the conditional is unsatisfiable and is optimized out.

This patch changes the attribute counting to use n_limits++ in the
attribute counting loop in the above example.

9f9581ba74 netlink: specs: fou: change local-v6/peer-v6 check
While updating the binary min-len implementation, I noticed that
the only user, should AFAICT be using exact-len instead.

In net/ipv4/fou_core.c FOU_ATTR_LOCAL_V6 and FOU_ATTR_PEER_V6
are only used for singular IPv6 addresses, and there are AFAICT
no known implementations trying to send more, it therefore
appears safe to change it to an exact-len policy.

This patch therefore changes the local-v6/peer-v6 attributes to
use an exact-len check, instead of a min-len check.

3bd4f98a4e mptcp: record subflows in RPS table
Accelerated Receive Flow Steering (aRFS) relies on sockets recording
their RX flow hash into the rps_sock_flow_table so that incoming packets
are steered to the CPU where the application runs.

With MPTCP, the application interacts with the parent MPTCP socket while
data is carried over per-subflow TCP sockets. Without recording these
subflows, aRFS cannot steer interrupts and RX processing for the flows
to the desired CPU.

Record all subflows in the RPS table by calling sock_rps_record_flow()
for each subflow at the start of mptcp_sendmsg(), mptcp_recvmsg() and
mptcp_stream_accept(), by using the new helper
mptcp_rps_record_subflows().

It does not by itself improve throughput, but ensures that IRQ and RX
processing are directed to the right CPU, which is a
prerequisite for effective aRFS.

929324913e net: Add rfs_needed() helper
Add a helper to check if RFS is needed or not. Allows to make the code a
bit cleaner and the next patch to have MPTCP use this helper to decide
whether or not to iterate over the subflows.

tun_flow_update() was calling sock_rps_record_flow_hash() regardless of
the state of rfs_needed. This was not really a bug as sock_flow_table
simply ends up being NULL and thus everything will be fine.
This commit here thus also implicitly makes tun_flow_update() respect
the state of rfs_needed.

b9a10f8764 soc: fixes for 6.17, part 2
These are mainly devicetree fixes for the rockchip and nxp platforms on
 arm64, addressing mistakes in the board and soc specific descriptions.
 In particular the newly added Rock 5T board required multiple bugfixes for
 PCIe and USB, while on the i.MX platform there are a number of regulator
 related fixes. The only other platforms with devicetree fixes are at91
 with a fixup for SD/MMC and a change to enable all the available UARTS
 on the Axiado reference board.
 
 Also on the at91 platform, a Kconfig change addresses a regression that
 stopped the DMA engine from working in 6.17-rc.
 
 Three drivers each have a simple bugfix, stopping incorrect behavior in
 op-tee firmware, the tee subsystem and the qualcomm mdt_loader.
 
 Two trivial MAINTAINERS file changes are needed to make sure that
 patches reach the correct maintainer, but don't change the actual
 responsibilities.

Merge tag 'soc-fixes-6.17-2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC fixes from Arnd Bergmann:
 "These are mainly devicetree fixes for the rockchip and nxp platforms
  on arm64, addressing mistakes in the board and soc specific
  descriptions.

  In particular the newly added Rock 5T board required multiple bugfixes
  for PCIe and USB, while on the i.MX platform there are a number of
  regulator related fixes. The only other platforms with devicetree
  fixes are at91 with a fixup for SD/MMC and a change to enable all the
  available UARTS on the Axiado reference board.

  Also on the at91 platform, a Kconfig change addresses a regression
  that stopped the DMA engine from working in 6.17-rc.

  Three drivers each have a simple bugfix, stopping incorrect behavior
  in op-tee firmware, the tee subsystem and the qualcomm mdt_loader.

  Two trivial MAINTAINERS file changes are needed to make sure that
  patches reach the correct maintainer, but don't change the actual
  responsibilities"

a5bd6ba30b sched_ext: Use cgroup_lock/unlock() to synchronize against cgroup operations
SCX hooks into CPU cgroup controller operations and read-locks
scx_cgroup_rwsem to exclude them while enabling and disable schedulers.
While this works, it's unnecessarily complicated given that
cgroup_[un]lock() are available and thus the cgroup operations can be locked
out that way.

Drop scx_cgroup_rwsem locking from the tg on/offline and cgroup [can_]attach
operations. Instead, grab cgroup_lock() from scx_cgroup_lock(). Drop
scx_cgroup_finish_attach() which is no longer necessary. Drop the now
unnecessary rcu locking and css ref bumping in scx_cgroup_init() and
scx_cgroup_exit().

As scx_cgroup_set_weight/bandwidth() paths aren't protected by
cgroup_lock(), rename scx_cgroup_rwsem to scx_cgroup_ops_rwsem and retain
the locking there.

This is overall simpler and will also allow enable/disable paths to
synchronize against cgroup changes independent of the CPU controller.
