ASoC: audio-graph-card2: add comment for format property
We don't need to have "format" property on DT any more if
CPU/Codec driver has .auto_selectable_formats settings
on snd_soc_dai_ops. The sample dtsi doesn't have it.
To avoid user confusion, this patch indicates it on comment.

d75e30dddf bpf: Fix issue in verifying allow_ptr_leaks
After we converted the capabilities of our networking-bpf program from
cap_sys_admin to cap_net_admin+cap_bpf, our networking-bpf program
failed to start. Because it failed the bpf verifier, and the error log
is "R3 pointer comparison prohibited".

A simple reproducer as follows,

SEC("cls-ingress")
int ingress(struct __sk_buff *skb)
{
	struct iphdr *iph = (void *)(long)skb->data + sizeof(struct ethhdr);

	if ((long)(iph + 1) > (long)skb->data_end)
		return TC_ACT_STOLEN;
	return TC_ACT_OK;
}

Per discussion with Yonghong and Alexei [1], comparison of two packet
pointers is not a pointer leak. This patch fixes it.

Our local kernel is 6.1.y and we expect this fix to be backported to
6.1.y, so stable is CCed.

78aabcb321 cpuidle: teo: Avoid unnecessary variable assignments
Notice that it is not necessary to assign tick_intercept_sum in every
iteration of the first loop over idle states in teo_select(), because
the intercept_sum value does not change after the assignment in a
given iteration of the loop, so its value after the last iteration of
the loop can be used for computing the tick_intercept_sum value
directly.

Modify the code accordingly.

No intentional functional impact.

Like a few other drivers, YMFPCI driver needs to clean up with
snd_card_free() call at an error path of the probe; otherwise the
other devres resources are released before the card and it results in
the UAF.

This patch uses the helper for handling the probe error gracefully.

Merge patch series "riscv: Allow userspace to directly access perf counters"
Alexandre Ghiti <alexghiti@rivosinc.com> says:

riscv used to allow direct access to cycle/time/instret counters,
bypassing the perf framework, this patchset intends to allow the user to
mmap any counter when accessed through perf.

**Important**: The default mode is now user access through perf only, not
the legacy so some applications will break. However, we introduce a sysctl
perf_user_access like arm64 does, which will allow to switch to the legacy
mode described above.

This version needs openSBI v1.3 *and* a kernel fix that went upstream lately
(https://lore.kernel.org/lkml/20230616114831.3186980-1-maz@kernel.org/T/).

* b4-shazam-merge:
  perf: tests: Adapt mmap-basic.c for riscv
  tools: lib: perf: Implement riscv mmap support
  Documentation: admin-guide: Add riscv sysctl_perf_user_access
  drivers: perf: Implement perf event mmap support in the SBI backend
  drivers: perf: Implement perf event mmap support in the legacy backend
  riscv: Prepare for user-space perf event mmap support

91b1ad0815 erofs: release ztailpacking pclusters properly
Currently ztailpacking pclusters are chained with FOLLOWED_NOINPLACE and
not recorded into the managed_pslots XArray.

After commit 7674a42f35 ("erofs: use struct lockref to replace
handcrafted approach"), ztailpacking pclusters won't be freed with
erofs_workgroup_put() anymore, which will cause the following issue:

BUG erofs_pcluster-1 (Tainted: G           OE     ): Objects remaining in erofs_pcluster-1 on __kmem_cache_shutdown()

Use z_erofs_free_pcluster() directly to free ztailpacking pclusters.

491b1105a8 erofs: adapt folios for z_erofs_readahead()
It's a straight-forward conversion except that readahead_folio()
will do folio_put() in advance but it doesn't matter since folios
are still locked.

As before, since file-backed folios (pages for now) are locked, so
we could temporarily use folio->private as an internal counter to
indicate split parts of each folio for the corresponding pclusters
to decompress.

When such counter becomes zero, the folio will be finally unlocked
(see compress.h and z_erofs_onlinepage_endio()).

dcba1b232e erofs: avoid obsolete {collector,collection} terms
{collector,collection} were once reserved in order to indicate different
runtime logical extent instance of multi-reference pclusters.

However, de-duplicated decompression has been landed in a more flexable
way, thus `struct z_erofs_collection` was formally removed in commit
87ca34a706 ("erofs: get rid of `struct z_erofs_collection'").

Let's handle the remaining leftovers, for example:
    `z_erofs_collector_begin` => `z_erofs_pcluster_begin`
    `z_erofs_collector_end` => `z_erofs_pcluster_end`

as well as some comments.  No logic changes.

02daa222fb platform: mellanox: Add initial support for PCIe based programming logic device
Extend driver to support logic implemented by FPGA device connected
through PCIe bus.

The motivation two support new generation of Nvidia COME module
equipped with Lattice LFD2NX-40 FPGA device.

In order to support new Nvidia COME module FPGA device driver
initialization flow is modified. In case FPGA device is detected,
system resources are to be mapped to this device, otherwise system
resources are to be mapped same as it has been done before for Lattice
LPC based CPLD.

FPGA device is associated with three PCIe devices:
- PCIe-LPC bridge for main register space access.
- PCIe-I2C bridge for I2C controller access.
- PCIe-JTAG bridge for JTAG access.

75e09ab420 platform: mellanox: mlx-platform: Modify power off callback
Extend platform power off callback with kernel_halt() call.

When powering off, the process involves setting a halt bit in the
register space, which is then activated after a certain delay and
power off auxiliary power. By invoking `kernel_halt()` within this
timeframe, the intention is to facilitate a clean system power-off
sequence.

Currently, of_nvmem_layout_get_container() returns NULL on error, or an
error pointer if either CONFIG_NVMEM or CONFIG_OF is turned off. We
should likely avoid this kind of mix for two reasons: to clarify the
intend and anyway fix the !CONFIG_OF which will likely always if we use
this helper somewhere else. Let's just return NULL when no layout is
found, we don't need an error value here.
