Pull regulator fixes from Mark Brown:
"The main thing here is a change to make sure that we don't try to
double resolve the supply of a regulator if we have two probes going
on simultaneously, plus an incremental fix on top of that to resolve a
lockdep issue it introduced.
There's also a patch from Dmitry Osipenko adding stubs for some
functions to avoid build issues in consumers in some configurations"

To ensure we handle situations in which multiple sensors of the same
model (and therefore _HID) are present in a system, we need to be able
to iterate over devices matching a known _HID but unknown _UID and _HRV
- add acpi_dev_get_next_match_dev() to accommodate that possibility and
change acpi_dev_get_first_match_dev() to simply call the new function
with a NULL starting point. Add an iterator macro for convenience.

OF, ACPI and software_nodes all implement graphs including nodes for ports
and endpoints. These are all intended to be named with a common schema,
as "port@n" and "endpoint@n" where n is an unsigned int representing the
index of the node. To ensure commonality across the subsystems, provide a
set of macros to define the format.

Intel Moorestown and Medfield are quite old Intel Atom based
32-bit platforms, which were in limited use in some Android phones,
tablets and consumer electronics more than eight years ago.
There are no bugs or problems ever reported outside from Intel
for breaking any of that platforms for years. It seems no real
users exists who run more or less fresh kernel on it. The commit
05f4434bc130 ("ASoC: Intel: remove mfld_machine") also in align
with this theory.
Due to above and to reduce a burden of supporting outdated drivers
we remove the support of outdated platforms completely.

When create the VMCI queue pair tracking data structures on the host
side, the IOCTL for creating the VMCI queue pair didn't validate
the queue pair size parameters. This change adds checks for this.
This avoids a memory allocation issue in qp_host_alloc_queue, as
reported by nslusarek@gmx.net. The check in qp_host_alloc_queue
has also been updated to enforce the maximum queue pair size
as defined by VMCI_MAX_GUEST_QP_MEMORY.
The fix has been verified using sample code supplied by
nslusarek@gmx.net.

The original driver, which can be seen at
commit 42f24d9d446a ("staging: regulator: add a regulator driver for HiSilicon 6421v600 SPMI PMIC")
had a complex logic to ensure that there won't be multiple power
enable/disable commands running at the same time. At the original
logic, it were ensured that:
- a next power up/down would wait for at least the on/off period;
- an extra delay would be granted. It turns that such extra delay
has a value of zero, but it was relying on gettimeofday()
call, which can take some time.
This was later simplified, but there are still some possible
issues. In order to avoid that, let's simply add a delay
to wait for the power up line to stabilize after powering up
a device.

The ORC metadata generated for UNWIND_HINT_FUNC isn't actually very
func-like. With certain usages it can cause stack state mismatches
because it doesn't set the return address (CFI_RA).
Also, users of UNWIND_HINT_RET_OFFSET no longer need to set a custom
return stack offset. Instead they just need to specify a func-like
situation, so the current ret_offset code is hacky for no good reason.
Solve both problems by simplifying the RET_OFFSET handling and
converting it into a more useful UNWIND_HINT_FUNC.
If we end up needing the old 'ret_offset' functionality again in the
future, we should be able to support it pretty easily with the addition
of a custom 'sp_offset' in UNWIND_HINT_FUNC.

Currently, _everything_ in cfg80211 holds the RTNL, and if you
have a slow USB device (or a few) you can get some bad lock
contention on that.
Fix that by re-adding a mutex to each wiphy/rdev as we had at
some point, so we have locking for the wireless_dev lists and
all the other things in there, and also so that drivers still
don't have to worry too much about it (they still won't get
parallel calls for a single device).
Then, we can restrict the RTNL to a few cases where we add or
remove interfaces and really need the added protection. Some
of the global list management still also uses the RTNL, since
we need to have it anyway for netdev management, but we only
hold the RTNL for very short periods of time here.

Drop the const qualifier from the static global cur_profile
pointer declaration.
This is a preparation patch for passing the cur_profile pointer as
parameter to the profile_get() and profile_set() callbacks so that
drivers dynamically allocating their driver-data struct, with their
platform_profile_handler struct embedded, can use this pointer to
get to their driver-data.
Note this also requires dropping the const from the pprof
platform_profile_register() function argument. Dropping this
const is not a problem, non of the queued up consumers of
platform_profile_register() actually pass in a const pointer.
