Update extcon next for v5.19

Detailed description for this pull request:
1. update extcon core driver
- extcon_get_extcon_dev() has been almost used to get the extcon device
on booting time. If extcon provider driver is probed at late time,
the extcon consumer driver get the -EPROBE_DEFER return value.
It requires the inefficient handling code of -EPROBE_DEFER.
Instead, extcon_get_extcon_dev() will return -EPROBE_DEFER
if the required extcon device is none. It makes the extcon consumer driver
to be simplified when getting extcon device.
- Register device after dev_set_drvdata because of accessing
the sysfs attributes at timing of between drv_set_data and device_register.
- Fix some kernel-doc comments of extcon functions.

2. update extcon provider driver
- Update extcon-intel-int3496.c
: Add support for controlling vbus power via regulator and support
to the extcon-intel-int3496.c driver to bind to devices without
an ACPi companion. And fix the minor clean-up.
- Use struct_size() helper on extcon-usbc-cros-ec.c
- Remove the disable irq operation in system sleep for using vbus/id
gpio as the wakeup source on extcon-usb-gpio.c
- Add support of SM5703 device by using existing extcon-sm5502.c
and rename i2c_devic_id from sm5703 to sm5703-muic to reduce confusion
between SM5703 MFD device and extcon device.
- Add usb role class support and add queue work sync before driver release
on extcon-ptn5150.c

MHI changes for v5.19

MHI Host
--------

Support for new modems:

 - Foxconn Cinterion MV32-WA/MV32-WB based on SDX62/SDX65
 - Telit FN980 v1 based on SDX55
 - Telit FN990 based on SDX65
 - Foxconn T99W373/T99W368 based on SDX62/SDX65

Core changes:

 - During the recycle of event ring elements, compute the ctxt_wp based on the
   local cached value instead of reading from shared memory. This is to prevent
   the possible corruption of the ctxt_wp as some of the endpoint devices could
   modify the value in shared memory.

 - Add sysfs support for resetting the endpoint based on the MHI spec. The MHI
   spec allows the host to hard reset the device in the case of an unrecoverable
   error and all other reset mechanisms have failed.

 - During MHI shutdown, wait for the endpoint device to enter the ready state
   post reset before proceeding. This is to avoid a possible race where host
   would remove the interrupt handler and device will send ready state
   interrupt, resulting in IOMMU fault.

 - Bail out updating the MHI register if the read has failed during
   read/modify/write.

 - Use mhi_write_reg() instead of mhi_write_reg_field() for writing the whole
   register fields in mhi_init_mmio().

MAINTAINERS change:

 - Since Qualcomm has moved the email domain for its employess from codeaurora

extcon: Fix extcon_get_extcon_dev() error handling

The extcon_get_extcon_dev() function returns error pointers on error,
NULL when it's a -EPROBE_DEFER defer situation, and ERR_PTR(-ENODEV)
when the CONFIG_EXTCON option is disabled.  This is very complicated for
the callers to handle and a number of them had bugs that would lead to
an Oops.

In real life, there are two things which prevented crashes.  First,
error pointers would only be returned if there was bug in the caller
where they passed a NULL "extcon_name" and none of them do that.
Second, only two out of the eight drivers will build when CONFIG_EXTCON
is disabled.

The normal way to write this would be to return -EPROBE_DEFER directly
when appropriate and return NULL when CONFIG_EXTCON is disabled.  Then
the error handling is simple and just looks like:

dev->edev = extcon_get_extcon_dev(acpi_dev_name(adev));
if (IS_ERR(dev->edev))
return PTR_ERR(dev->edev);

For the two drivers which can build with CONFIG_EXTCON disabled, then
extcon_get_extcon_dev() will now return NULL which is not treated as an
error and the probe will continue successfully.  Those two drivers are
"typec_fusb302" and "max8997-battery".  In the original code, the
typec_fusb302 driver had an 800ms hang in tcpm_get_current_limit() but
now that function is a no-op.  For the max8997-battery driver everything
should continue working as is.

coresight: cpu-debug: Replace mutex with mutex_trylock on panic notifier

The panic notifier infrastructure executes registered callbacks when
a panic event happens - such callbacks are executed in atomic context,
with interrupts and preemption disabled in the running CPU and all other
CPUs disabled. That said, mutexes in such context are not a good idea.

This patch replaces a regular mutex with a mutex_trylock safer approach;
given the nature of the mutex used in the driver, it should be pretty
uncommon being unable to acquire such mutex in the panic path, hence
no functional change should be observed (and if it is, that would be
likely a deadlock with the regular mutex).

soundwire: bus: pm_runtime_request_resume on peripheral attachment

In typical use cases, the peripheral becomes pm_runtime active as a
result of the ALSA/ASoC framework starting up a DAI. The parent/child
hierarchy guarantees that the manager device will be fully resumed
beforehand.

There is however a corner case where the manager device may become
pm_runtime active, but without ALSA/ASoC requesting any functionality
from the peripherals. In this case, the hardware peripheral device
will report as ATTACHED and its initialization routine will be
executed. If this initialization routine initiates any sort of
deferred processing, there is a possibility that the manager could
suspend without the peripheral suspend sequence being invoked: from
the pm_runtime framework perspective, the peripheral is *already*
suspended.

To avoid such disconnects between hardware state and pm_runtime state,
this patch adds an asynchronous pm_request_resume() upon successful
attach/initialization which will result in the proper resume/suspend
sequence to be followed on the peripheral side.

The detailed analysis shows the RT711 codec driver scheduling a jack
detection workqueue while attaching during a spurious pm_runtime

The direct link between this ACPI patch and a spurious pm_runtime

the ACPI device linked list management modifies the order in which the
pm_runtime device status is checked and exposes a race condition that
was probably present for a very long time, but was not identified.

we deal with the status change and program deviceA device number to a

5) deviceB attaches as device0, the device0 status seen by the

6) we clear the CDNS_MCP_SLAVE_INTSTAT0/1 registers -> we will never detect

Note that the deprecated of_reset_control_get() and
