intel-gpio for v5.18-1

* Set IRQ bus token in gpio-crystalcove to avoid debugfs error
* Check return value of kstrdup() in gpio-merrifield to error out earlier
* Clean up couple of drivers from unneeded of_node usage
* Allow gpio-tps68470 to be built as module to reduce memory foot print

Instead of keeping specific data structure for IRQ trigger types, switch
to array of trigger names and use index as a type.

The code is in maintenance mode and that array is not going to grow.

devm_kstrdup() returns pointer to allocated string on success, NULL on
failure. So it is better to check the return value of it.

Before, if devm_kstrdup() fails, pinctrl_dev_name will be NULL, then the
retval below will be a negative error-code (inside gpiochip_add_pin_range(),
pinctrl_find_and_add_gpio_range()->get_pinctrl_dev_from_devname() will
finally check pinctrl_dev_name and return an error), so the failure of
devm_kstrdup() can be only implicitly caught after a long call chain.

While this patch is to explicitly catch the failure in time.

For the CRC PMIC we end up with multiple irq-domains with the same fwnode.
One for the irqchip which demultiplexes the actual PMIC interrupt into
interrupts for the various cells (known as the level 1 interrupts);

And 2 more for the irqchips which are part of the crystal_cove_gpio
and crystal_cove_charger cells.

This leads to the following error being printed when
CONFIG_GENERIC_IRQ_DEBUGFS is enabled:
 debugfs: File '\_SB.I2C7.PMIC' in directory 'domains' already present!

Set the bus token of the main IRQ domain to DOMAIN_BUS_WIRED to avoid
this error, this also allows irq_find_matching_fwspec() to find the
right domain if necessary.

Note all 3 domain registering drivers need to set the IRQ domain bus token.
This is necessary because the IRQ domain code defaults to creating
the debugfs dir with just the fwnode name and then renames it when
the bus token is set. So each one starts with the same default name and
all 3 must be given a different name to avoid problems when one of the
other drivers loads and starts with the same default name.

Pull ftrace fix from Steven Rostedt:
 "Fix s390 breakage from sorting mcount tables.

  The latest merge of the tracing tree sorts the mcount table at build
  time. But s390 appears to do things differently (like always) and
  replaces the sorted table back to the original unsorted one. As the
  ftrace algorithm depends on it being sorted, bad things happen when it
  is not, and s390 experienced those bad things.

  Add a new config to tell the boot if the mcount table is sorted or
  not, and allow s390 to opt out of it"

* tag 'trace-v5.17-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace:
  ftrace: Fix assuming build time sort works for s390

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.

Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.

Before said patch:

  perf record -c 10000 -e arm_spe_0// -- sleep 1

Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.

This patch restores the previous behaviour for non-libpfm4 events.

Since b8c96a6b ("certs: simplify $(srctree)/ handling and remove
config_filename macro"), when CONFIG_MODULE_SIG_KEY is empty,
signing_key.x509 fails to build:

    CERT    certs/signing_key.x509
  Usage: extract-cert <source> <dest>
  make[1]: *** [certs/Makefile:78: certs/signing_key.x509] Error 2
  make: *** [Makefile:1831: certs] Error 2

Pass "" to the first argument of extract-cert to fix the build error.

When CONFIG_MODULE_SIG_KEY is PKCS#11 URL (pkcs11:*), signing_key.x509
fails to build:

  certs/Makefile:77: *** target pattern contains no '%'.  Stop.

Due to the typo, $(X509_DEP) contains a colon.

Fix it.

This reverts commit cd8c917a.

Commit 129ab0d2 ("kbuild: do not quote string values in
include/config/auto.conf") provided the final solution.

Now reverting the temporary workaround.

As linux/nfc.h userspace compilation was finally fixed by commits
79b69a83 ("nfc: uapi: use kernel size_t to fix user-space builds")
and 7175f02c ("uapi: fix linux/nfc.h userspace compilation errors"),
there is no need to keep the compile-test exception for it in
usr/include/Makefile.
