driver core: Flow the return code from ->probe() through to sysfs bind

Currently really_probe() returns 1 on success and 0 if the probe() call
fails. This return code arrangement is designed to be useful for
__device_attach_driver() which is walking the device list and trying every
driver. 0 means to keep trying.

However, it is not useful for the other places that call through to
really_probe() that do actually want to see the probe() return code.

For instance bind_store() would be better to return the actual error code
from the driver's probe method, not discarding it and returning -ENODEV.

Reorganize things so that really_probe() returns the error code from
->probe as a (inverted) positive number, and 0 for successful attach.

With this, __device_attach_driver can ignore the (positive) probe errors,
return 1 to exit the loop for a successful binding and pass on the
other negative errors, while device_driver_attach simplify inverts the
positive errors and returns all errors to the sysfs code.

driver core: Pull required checks into driver_probe_device()

Checking if the dev is dead or if the dev is already bound is a required
precondition to invoking driver_probe_device(). All the call chains
leading here duplicate these checks.

Add it directly to driver_probe_device() so the precondition is clear and
remove the checks from device_driver_attach() and
__driver_attach_async_helper().

The other call chain going through __device_attach_driver() does have
these same checks but they are inlined into logic higher up the call stack
and can't be removed.

The sysfs uAPI call chain starting at bind_store() is a bit confused
because it reads dev->driver unlocked and returns -ENODEV if it is !NULL,
otherwise it reads it again under lock and returns 0 if it is !NULL. Fix
this to always return -EBUSY and always read dev->driver under its lock.

Done in preparation for the next patches which will add additional
callers to driver_probe_device() and will need these checks as well.

ALSA/ASoC/SOF/SoundWire: fix Kconfig issues

In January, Intel kbuild bot and Arnd Bergmann reported multiple
issues with randconfig. This patchset builds on Arnd's suggestions to

a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
and sof-pci-dev become helpers. This will result in minor changes
required for developers/testers, i.e. modprobe snd-sof-pci will no
longer result in a probe. The SOF CI was already updated to deal with
this module dependency change and introduction of new modules.

b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
required to detect SoundWire presence in ACPI tables to sound/hda.

Merge tag 'driver-core-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

Pull driver core / debugfs update from Greg KH:
"Here is the "big" driver core and debugfs update for 5.12-rc1

This set of driver core patches caused a bunch of problems in
linux-next for the past few weeks, when Saravana tried to set
fw_devlink=on as the default functionality. This caused a number of
systems to stop booting, and lots of bugs were fixed in this area for
almost all of the reported systems, but this option is not ready to be
turned on just yet for the default operation based on this testing, so
I've reverted that change at the very end so we don't have to worry
about regressions in 5.12

We will try to turn this on for 5.13 if testing goes better over the
next few months.

Other than the fixes caused by the fw_devlink testing in here, there's
not much more:

- debugfs fixes for invalid input into debugfs_lookup()

- kerneldoc cleanups

- warn message if platform drivers return an error on their remove
callback (a futile effort, but good to catch).

All of these have been in linux-next for a while now, and the
regressions have gone away with the revert of the fw_devlink change"
