"Nothing major here, there are two drivers that need review and did not

It's valid to use the PCA955x devices just for GPIOs and not for LEDs.
In this case, as PCA955X_TYPE_GPIO is now equivalent to
PCA955X_TYPE_NONE, remove the test for whether we have any child nodes
specified in the devicetree.
A consequence of this is it's now possible to bind the driver to a
PCA955x device when dynamically instantiated through the I2C subsystem's
`new_device` interface.

The devicetree binding allows specifying which pins are GPIO vs LED.
Limiting the instantiated gpiochip to just these pins as the driver
currently does requires an arbitrary mapping between pins and GPIOs, but
such a mapping is not implemented by the driver. As a result,
specifying GPIOs in such a way that they don't map 1-to-1 to pin indexes
does not function as expected.
Establishing such a mapping is more complex than not and even if we did,
doing so leads to a slightly hairy userspace experience as the behaviour
of the PCA955x gpiochip would depend on how the pins are assigned in the
devicetree. Instead, always expose all pins via the gpiochip to provide
a stable interface and track which pins are in use.
Specifying a pin as `type = <PCA955X_TYPE_GPIO>;` in the devicetree
becomes a no-op.
I've assessed the impact of this change by looking through all of the
affected devicetrees as of the tag leds-5.15-rc1:
```
$ git grep -l 'pca955[0123]' $(find . -name dts -type d)
arch/arm/boot/dts/aspeed-bmc-ibm-everest.dts
arch/arm/boot/dts/aspeed-bmc-ibm-rainier.dts
arch/arm/boot/dts/aspeed-bmc-opp-mihawk.dts
arch/arm/boot/dts/aspeed-bmc-opp-mowgli.dts
arch/arm/boot/dts/aspeed-bmc-opp-swift.dts
arch/arm/boot/dts/aspeed-bmc-opp-tacoma.dts
arch/arm/boot/dts/aspeed-bmc-opp-witherspoon.dts
```
These are all IBM-associated platforms. I've analysed both the
devicetrees and schematics where necessary to determine whether any
systems hit the hazard of the current broken behaviour. For the most
part, the systems specify the pins as either all LEDs or all GPIOs, or
at least do so in a way such that the broken behaviour isn't exposed.
The main counter-point to this observation is the Everest system whose
devicetree describes a large number of PCA955x devices and in some cases
has pin assignments that hit the hazard. However, there does not seem to
be any use of the affected GPIOs in the userspace associated with
Everest.
Regardless, any use of the hazardous GPIOs in Everest is already broken,
so let's fix the interface and then fix any already broken userspace
with it.

The only difference between returning zero or a non-zero value is that
for the non-zero case the i2c will print a generic error message
("remove failed (-ESOMETHING), will be ignored").
In this case however the driver itself already emitted a more helpful
error message, so the additional error message isn't helpful at all.
The long-term goal is to make the i2c remove callback return void, making
all implementations return 0 is preparatory work for this change.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

invokes led_trigger_event() which may invoke the callback of the actual driver.
That driver can acquire a spinlock_t which is okay on kernel without
PREEMPT_RT. On a PREEMPT_RT enabled kernel this lock is turned into a

Even with the previous commit 27af8e2c90
("leds: trigger: fix potential deadlock with libata")
to this file, we still get lockdep unhappy, and Boqun
explained the report here:
https://lore.kernel.org/r/YNA+d1X4UkoQ7g8a@boqun-archlinux
Effectively, this means that the read_lock_irqsave() isn't
enough here because another CPU might be trying to do a
write lock, and thus block the readers.
This is all pretty messy, but it doesn't seem right that
the LEDs framework imposes some locking requirements on
users, in particular we'd have to make the spinlock in the
iwlwifi driver always disable IRQs, even if we don't need
that for any other reason, just to avoid this deadlock.
Since writes to the led_cdevs list are rare (and are done
by userspace), just switch the list to RCU. This costs a
synchronize_rcu() at removal time so we can ensure things
are correct, but that seems like a small price to pay for
getting lock-free iterations and no deadlocks (nor any
locking requirements imposed on users.)

Some 2-in-1s with a detachable (USB) keyboard(dock) have mute-LEDs in
the speaker- and/or mic-mute keys on the keyboard.
Examples of this are the Lenovo Thinkpad10 tablet (with its USB kbd-dock)
and the HP x2 10 series.
The detachable nature of these keyboards means that the keyboard and
thus the mute LEDs may show up after the user (or userspace restoring
old mixer settings) has muted the speaker and/or mic.
Current LED-class devices with a default_trigger of "audio-mute" or
"audio-micmute" initialize the brightness member of led_classdev with
ledtrig_audio_get() before registering the LED.
This makes the software state after attaching the keyboard match the
actual audio mute state, e.g. cat /sys/class/leds/foo/brightness will
show the right value.
But before this commit nothing was actually calling the led_classdev's
brightness_set[_blocking] callback so the value returned by
ledtrig_audio_get() was never actually being sent to the hw, leading
to the mute LEDs staying in their default power-on state, after
attaching the keyboard, even if ledtrig_audio_get() returned a different
state.
This could be fixed by having the individual LED drivers call
brightness_set[_blocking] themselves after registering the LED,
but this really is something which should be done by a led-trigger
activate callback.
Add an activate callback for this, fixing the issue of the
mute LEDs being out of sync after (re)attaching the keyboard.
