8f512c3113 media: i2c: ds90ub960: Add error handling to multiple places
The driver is missing checks for i2c read/write errors in many places.
Now that we have added the err parameter to the read/write functions in
the previous patch, add error handling to all the missing places.

24868501a7 media: i2c: ds90ub9xx: Add err parameter to read/write funcs
To make future error handling in the drivers easier, add "int *err"
parameter to all the i2c register access functions. It functions the
same was as with e.g. CCI reg write/read helpers.

This was accomplished with the following semantic patch:

  @@
  identifier FUNC =~ "^ub9.._(rxport_|txport_|ind_)?(read|write|update_bits)(16|_ind)?$";

  +			*err = ret;

When setting the sink pad's stream format, set_fmt accidentally changes
the returned format's code to 'outcode', while the purpose is to only

0e7db503c5 accel/ivpu: Implement heartbeat-based TDR mechanism
Introduce a heartbeat-based Timeout Detection and Recovery (TDR) mechanism.
The enhancement aims to improve the reliability of device hang detection by
monitoring heartbeat updates.

Each progressing inference will update heartbeat counter allowing driver to
monitor its progression. Limit maximum number of reschedules when heartbeat
indicates progression to 30. This increases the maximum running time of
single inference to about 60 seconds.

The heartbeat mechanism provides a more robust method for detecting device
hangs, potentially reducing false positive recoveries due to long running
inferences.

9bbb8a07fd tools/hv: update route parsing in kvp daemon
After recent changes in the VM network stack, the host fails to
display the IP addresses of the VM. As a result the "IP Addresses"
column in the "Networking" tab in the Windows Hyper-V Manager is
empty. This is caused by a change in the expected output of the
"ip route show" command. Previously the gateway address was shown
in the third row. Now the gateway addresses might be split into
several lines of output. As a result, the string "ra" instead of
an IP address is sent to the host.

To me more specific, a VM with the wellknown wicked network
managing tool still shows the expected output in recent openSUSE
Tumbleweed snapshots:

ip a show dev uplink;ip -4 route show;ip -6 route show
2: uplink: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state ...

A similar VM, but with NetworkManager as network managing tool:

Adjust the route parsing to use a single line for each line of
output. Also use a single shell invocation to retrieve both IPv4
and IPv6 information. The actual IP addresses are expected after
the "via" keyword.

bf0b4f1526 crypto: riscv - Use SYM_FUNC_START for functions only called directly
After some recent changes to the RISC-V crypto code that turned some
indirect function calls into direct ones, builds with CONFIG_CFI_CLANG
fail with:

  ld.lld: error: undefined symbol: __kcfi_typeid_sm3_transform_zvksh_zvkb
  >>> referenced by arch/riscv/crypto/sm3-riscv64-zvksh-zvkb.o:(.text+0x2) in archive vmlinux.a

  ld.lld: error: undefined symbol: __kcfi_typeid_sha512_transform_zvknhb_zvkb
  >>> referenced by arch/riscv/crypto/sha512-riscv64-zvknhb-zvkb.o:(.text+0x2) in archive vmlinux.a

  ld.lld: error: undefined symbol: __kcfi_typeid_sha256_transform_zvknha_or_zvknhb_zvkb
  >>> referenced by arch/riscv/crypto/sha256-riscv64-zvknha_or_zvknhb-zvkb.o:(.text+0x2) in archive vmlinux.a

As these functions are no longer indirectly called (i.e., have their
address taken), the compiler will not emit __kcfi_typeid symbols for
them but SYM_TYPED_FUNC_START expects these to exist at link time.

Switch the definitions of these functions to use SYM_FUNC_START, as they
no longer need kCFI type information since they are only called
directly.

a747c4dd2a arm64: dts: imx8mn-beacon: Set SAI5 MCLK direction to output for HDMI audio
The HDMI bridge chip fails to generate an audio source due to the SAI5
master clock (MCLK) direction not being set to output. This prevents proper
clocking of the HDMI audio interface.

Add the `fsl,sai-mclk-direction-output` property to the SAI5 node to ensure
the MCLK is driven by the SoC, resolving the HDMI sound issue.

f40139fde5 ublk: fix race between io_uring_cmd_complete_in_task and ublk_cancel_cmd
ublk_cancel_cmd() calls io_uring_cmd_done() to complete uring_cmd, but
we may have scheduled task work via io_uring_cmd_complete_in_task() for
dispatching request, then kernel crash can be triggered.

Fix it by not trying to canceling the command if ublk block request is
started.

4acf6d4f6a Merge branch 'fix-netdevim-to-correctly-mark-napi-ids'
Joe Damato says:

====================
Fix netdevim to correctly mark NAPI IDs

This series fixes netdevsim to correctly set the NAPI ID on the skb.
This is helpful for writing tests around features that use
SO_INCOMING_NAPI_ID.

In addition to the netdevsim fix in patch 1, patches 2 & 3 do some self
test refactoring and add a test for NAPI IDs. The test itself (patch 3)
introduces a C helper because apparently python doesn't have
socket.SO_INCOMING_NAPI_ID.

f71c549b26 netdevsim: Mark NAPI ID on skb in nsim_rcv
Previously, nsim_rcv was not marking the NAPI ID on the skb, leading to
applications seeing a napi ID of 0 when using SO_INCOMING_NAPI_ID.

To add to the userland confusion, netlink appears to correctly report
the NAPI IDs for netdevsim queues but the resulting file descriptor from
a call to accept() was reporting a NAPI ID of 0.
