When the part is reset in component_probe, do not forget to reinit the
regcache, otherwise the cache can get out of sync with the part's
actual state. This fix is similar to commit 0a0342ede3
("ASoC: tas2770: Reinit regcache on reset") which concerned the
tas2770 driver.

We don't actually support configuring the PDM input right now. Rather,
this is useful as a hack.
On Apple Silicon machines, amps are split between two I2S buses which
are logically ANDed internally at the SoC. Odd and even slot groups are
driven by amps on either bus respectively. Since the signals are ANDed,
unused slot groups must be driven as zero to avoid corrupting the data
from the other side.
On most recent machines (TAS2764-based), this is accomplished using the
"SDOUT zero mask" feature of that chip. Unfortunately, TAS2770 does not
support this. It does support zeroing out *all* unused slots, which
works well for machines with a single amp per I2S bus. That is all,
except one.
The 13" M1 MacBook Pro is the only machine using TAS2770 and two amps
per I2S bus:
L Bus: SPK0I SPK0V Hi-Z Hi-Z SPK2I SPK2V Hi-Z Hi-Z
R Bus: Hi-Z Hi-Z SPK1I SPK2V Hi-Z Hi-Z SPK3I SPK3V
To ensure uncorrupted data, we need to force all the Hi-Z periods to
zero. We cannot use the "force all zero" feature, as that would cause a
bus conflict between both amps. We can use the pull-down feature, but
that leaves a few bits of garbage on the trailing edge of the speaker
data, since the pull-down is weak.
This is where the PDM transmit feature comes in. With PDM grounded and
disabled (the default state), the PDM slot is transmitted as all zeroes.
We can use that to force a zero 16-bit slot after the voltage data for
each speaker, cleaning it up. Then the pull-down ensures the line stays
low for the subsequent slot:
L Bus: SPK0I SPK0V PDM0 PulDn SPK2I SPK2V PDM0 PulDn
R Bus: PDM0 PulDn SPK1I SPK2V PDM0 PulDn SPK3I SPK3V
Yes, this is a horrible hack, but it beats adding dummy slots that would
be visible to the userspace capture side. There may be some other way to
fix the logical AND behavior on the MCA side... that would make this
unnecessary.
("How does Apple deal with this"? - they don't, macOS does not use
IVSENSE on TAS2770 machines even though it's physically wired up,
but we want to do so on Linux.)

The ISENSE/VSENSE blocks are only powered up when the amplifier
transitions from shutdown to active. This means that if those controls
are flipped on while the amplifier is already playing back audio, they
will have no effect.
Fix this by forcing a power cycle around transitions in those controls.

Issue:
When multiple audio streams share a common BE DAI, the BE DAI
widget can be powered up before its hardware parameters are configured.
This incorrect sequence leads to intermittent pcm_write errors.
For example, the below Tegra use-case throws an error:
aplay(2 streams) -> AMX(mux) -> ADX(demux) -> arecord(2 streams),
here, 'AMX TX' and 'ADX RX' are common BE DAIs.
For above usecase when failure happens below sequence is observed:
aplay(1) FE open()
- BE DAI callbacks added to the list
- BE DAI state = SND_SOC_DPCM_STATE_OPEN
aplay(2) FE open()
- BE DAI callbacks are not added to the list as the state is
already SND_SOC_DPCM_STATE_OPEN during aplay(1) FE open().
aplay(2) FE hw_params()
- BE DAI hw_params() callback ignored
aplay(2) FE prepare()
- Widget is powered ON without BE DAI hw_params() call
aplay(1) FE hw_params()
- BE DAI hw_params() is now called
Fix:
Add BE DAIs in the list if its state is either SND_SOC_DPCM_STATE_OPEN
or SND_SOC_DPCM_STATE_HW_PARAMS as well.
It ensures the widget is powered ON after BE DAI hw_params() callback.

Fix a shutdown WARNING in bch2_dev_free caused by active write I/O
references (ca->io_ref[WRITE]) on a device being freed.
The problem occurs when:
- The filesystem is marked read-only (BCH_FS_rw clear in c->flags).
- A subsequent operation (e.g., error handling for device removal)
incorrectly tries to grant write references back to a device.
- During final shutdown, the read-only flag causes the system to skip
stopping write I/O references (bch2_dev_io_ref_stop(ca, WRITE)).
- The leftover active write reference triggers the WARN_ON in
bch2_dev_free.
Prevent this by checking if the filesystem is read-only before
attempting to grant write references to a device in the problematic
code path. Ensure consistency between the filesystem state flag
and the device I/O reference state during shutdown.

Since objtool's inception, frame pointer warnings have been manually
silenced for __arch_hweight*() to allow those functions' inline asm to
avoid using ASM_CALL_CONSTRAINT.
The potentially dubious reasoning for that decision over nine years ago
was that since !X86_FEATURE_POPCNT is exceedingly rare, it's not worth
hurting the code layout for a function call that will never happen on
the vast majority of systems.
However, those functions actually started using ASM_CALL_CONSTRAINT with
the following commit:
194a613088 ("x86/hweight: Use ASM_CALL_CONSTRAINT in inline asm()")
And rightfully so, as it makes the code correct. ASM_CALL_CONSTRAINT
will soon have no effect for non-FP configs anyway.
With ASM_CALL_CONSTRAINT in place, ANNOTATE_IGNORE_ALTERNATIVE no longer
has a purpose for the hweight functions. Remove it.
