9a0c58d025 drivers/usb/misc: refactor min with min_t
Ensure type safety by using min_t() instead of min().

Also add the explicit `unsigned int` as scripts/checkpatch.pl warns about:

	WARNING: Prefer 'unsigned int' to bare use of 'unsigned'

ASoC: amd: ps: fix the pcm device numbering for acp 6.3 platform
Fixed PCM device numbering is required for defining common alsa ucm
changes for generic soundwire machine driver for legacy(No DSP) stack.

Ex: For Headphone playback use case, use PCM device number as 0.
For Headset mic Capture use case, PCM device number as 1.

Set the 'use_dai_pcm_id' flag true in soundwire dma driver for acp 6.3
platform. This will fix the pcm device numbering based on dai_link->id.

implement the AMD 3D V-Cache Optimizer, which allows selecting either:

Frequency mode: cores within the faster CCD are prioritized before
those in the slower CCD.

Cache mode: cores within the larger L3 CCD are prioritized before
those in the smaller L3 CCD.

e7583c5f8d s390/asm: Helper macros for flag output operand handling
Since gcc supports flag out operands for inline assemblies there is always
the question when this feature should be used and if it is worth all the
ifdefs that come with that.

In order to avoid that provide similar macros like x86 which can be used
for all inline assemblies which extract the condition code. Depending on
compiler features the generated code will either always contain an ipm+srl
instruction pair, which extracts the condition code, or alternatively let
the compiler handle this completely.

2f4b3b83b8 s390/cio: Externalize full CMG characteristics
The current "measurement_chars" CHPID sysfs attribute exposes only a
limited, validity-filtered portion of data from the associated Channel-
Measurements Characteristics Block (CMCB). New machine models add data
that is relevant for userspace tooling to the "header"-portion of the
CMCB. This data that is not currently accessible to userspace.

To prevent having to add new sysfs attributes whenever a new bit of data
is added to the CMCB "header", add a new sysfs attribute named
"measurement_chars_full" that exposes the full, unfiltered CMCB.

spi: cs42l43: Add GPIO speaker id support to the bridge configuration

Attempt to read a spk-id value using the GPIO method when a usable

Obtaining the spk-id value has been moved earlier in the function to the

In some cases the code uses goto labels to just return an error code.
Replace those with direct return:s and drop unneeded goto labels.

ab899a0ec3 pinctrl: cy8c95x0: embed iterator to the for-loop
When we iterate through nports the iterator variable is effectively
being not used outside of the loop. Make it clear by moving its definition
into the for-loop. This makes code cleaner as well.

e1b47291bd pinctrl: cy8c95x0: Use temporary variable for struct device
Use a temporary variable for the struct device pointers to avoid
dereferencing. This makes code a bit neater.

f8bd5383d8 pinctrl: cy8c95x0: use flexible sleeping in reset function
The device reset assert and deassert length was created by usleep_range()
but that does not ensure optimal handling of all the different values from
device tree properties. By switching to the new flexible sleeping helper
function, fsleep(), the correct delay function is called depending on
delay length, e.g. udelay(), usleep_range() or msleep().

While at it, move out GPIO consumer name setting of the reset conditional,
the all necessary checks are already done there, so logically that call is
not related to the reset sequence.

c13411c6fa pinctrl: cy8c95x0: switch to using devm_regulator_get_enable()
The driver does not actively manage regulator state past probe() time,
so we can use devm_regulator_get_enable() to simplify the code.

8d9ffb2fe6 x86/mm: Fix a kdump kernel failure on SME system when CONFIG_IMA_KEXEC=y
The kdump kernel is broken on SME systems with CONFIG_IMA_KEXEC=y enabled.
Debugging traced the issue back to

  b69a2afd5a ("x86/kexec: Carry forward IMA measurement log on kexec").

Testing was previously not conducted on SME systems with CONFIG_IMA_KEXEC
enabled, which led to the oversight, with the following incarnation:

...
  ima: No TPM chip found, activating TPM-bypass!
  Loading compiled-in module X.509 certificates

Adding debug printks showed that the stored addr and size of ima_kexec buffer
are not decrypted correctly like:

  ima: ima_load_kexec_buffer, buffer:0xcfacfdfe6660003e, size:0xe48066052d5df359

Three types of setup_data info

  — SETUP_EFI,
  - SETUP_IMA, and
  - SETUP_RNG_SEED

are passed to the kexec/kdump kernel. Only the ima_kexec buffer
experienced incorrect decryption. Debugging identified a bug in
early_memremap_is_setup_data(), where an incorrect range calculation
occurred due to the len variable in struct setup_data ended up only
representing the length of the data field, excluding the struct's size,
and thus leading to miscalculation.

Address a similar issue in memremap_is_setup_data() while at it.
