[PATCH AUTOSEL 6.13 01/16] ASoC: SOF: Intel: hda-dai: Ensure DAI widget is valid during params
From: Bard Liao yung-chuan.liao@linux.intel.com
[ Upstream commit 569922b82ca660f8b24e705f6cf674e6b1f99cc7 ]
Each cpu DAI should associate with a widget. However, the topology might not create the right number of DAI widgets for aggregated amps. And it will cause NULL pointer deference. Check that the DAI widget associated with the CPU DAI is valid to prevent NULL pointer deference due to missing DAI widgets in topologies with aggregated amps.

The verifier log when leaking resources on BPF_EXIT may be a bit confusing, as it's a problem only when finally existing from the main prog, not from any of the subprogs. Hence, update the verifier error string and the corresponding selftests matching on it.

[ Upstream commit 4b5bc2ec9a239bce261ffeafdd63571134102323 ]
Now that the following fix:
d0ceea662d45 ("x86/mm: Add _PAGE_NOPTISHADOW bit to avoid updating userspace page tables")
stops kernel_ident_mapping_init() from scribbling over the end of a 4KiB PGD by assuming the following 4KiB will be a userspace PGD, there's no good reason for the kexec PGD to be part of a single 8KiB allocation with the control_code_page.
( It's not clear that that was the reason for x86_64 kexec doing it that way in the first place either; there were no comments to that effect and it seems to have been the case even before PTI came along. It looks like it was just a happy accident which prevented memory corruption on kexec. )
Either way, it definitely isn't needed now. Just allocate the PGD separately on x86_64, like i386 already does.

Add the compatible for the separate IOMMU on SDM670 for the Adreno GPU.
This IOMMU has the compatible strings:
"qcom,sdm670-smmu-v2", "qcom,adreno-smmu", "qcom,smmu-v2"
While the SMMU 500 doesn't need an entry for this specific SoC, the SMMU v2 compatible should have its own entry, as the fallback entry in arm-smmu.c handles "qcom,smmu-v2" without per-process page table support unless there is an entry here. This entry can't be the "qcom,adreno-smmu" compatible because dedicated GPU IOMMUs can also be SMMU 500 with different handling.

Hi Sasha,
This change requires changes in the perf tool. The issue is the -1 gets written to perf.data files in the topology, the -errno value is "corrupt." Because of this, I'd suggest not backporting this change.
Thanks, Ian

kmemleak noticed that the iopf queue allocated deep down within arm_smmu_init_structures() can be leaked by a subsequent error return from arm_smmu_device_probe(). Furthermore, after arm_smmu_device_reset() we will also leave the SMMU enabled with an empty Stream Table, silently blocking all DMA. This proves rather annoying for debugging said probe failure, so let's handle it a bit better by putting the SMMU back into (more or less) the same state as if it hadn't probed at all.

Not all devices have an ACPI companion fwnode, so adev might be NULL. This can e.g. (theoretically) happen when a user manually binds one of the int3472 drivers to another i2c/platform device through sysfs.
Add a check for adev not being set and return -ENODEV in that case to avoid a possible NULL pointer deref in skl_int3472_get_acpi_buffer().

commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port" log severity") ignores -EINVAL error message on common soc_pcm_ret(). It is used from many functions, ignoring -EINVAL is over-kill.
The reason why -EINVAL was ignored was it really should only be used upon invalid parameters coming from userspace and in that case we don't want to log an error since we do not want to give userspace a way to do a denial-of-service attack on the syslog / diskspace.
So don't use soc_pcm_ret() on .prepare callback is better idea.

[ Upstream commit f6bfa25c6665f8721421ea94fe506cc22f1d4b43 ]
On the Acer Swift SFG14-41, the events 8 - 1 and 8 - 0 are printed on AC connect/disconnect. Ignore those events to avoid spamming the kernel log with error messages.
