As well as its sibling of_device_get_match_data() has no such checks,
no need to do it in acpi_get_match_data().

First of all, we are not supposed to call fwnode API like this without
driver attached.

Second, since __acpi_match_device() does check input parameter there is
no need to duplicate it outside.

And last but not least one, the API should still serve the cases when
ACPI device is enumerated via PRP0001. In such case driver has neither
ACPI table nor driver data there.

When __acpi_match_device() is called it would be possible to have
ACPI ID table a NULL pointer. To avoid potential dereference,
check for this before traverse.

While here, remove redundant 'else'.

Note, this patch implies a bit of refactoring acpi_of_match_device()
to return pointer to OF ID when matched followed by refactoring
__acpi_match_device() to return either ACPI or OF ID when matches.

Commit 66259146 (ACPI / EC: Drop EC noirq hooks to fix a
regression) modified the ACPI EC driver so that it doesn't switch
over to busy polling mode during noirq stages of system suspend and
resume in an attempt to fix an issue resulting from that behavior.

However, that modification introduced a system resume regression on
Thinkpad X240, so make the EC driver switch over to the polling mode
during noirq stages of system suspend and resume again, which
effectively reverts the problematic commit.

This is the mindless scripted replacement of kernel use of POLL*

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

SPCR is currently only enabled or ARM64 and x86 can use SPCR to setup
an early console.

General fixes include updating Documentation & Kconfig (for x86),
updating comments, and changing parse_spcr() to acpi_parse_spcr(),
and earlycon_init_is_deferred to earlycon_acpi_spcr_enable to be
more descriptive.

On x86, many systems have a valid SPCR table but the table version is
not 2 so the table version check must be a warning.

On ARM64 when the kernel parameter earlycon is used both the early console
and console are enabled.  On x86, only the earlycon should be enabled by
by default.  Modify acpi_parse_spcr() to allow options for initializing
the early console and console separately.

This is because if there's only one online CPU, the MSR_PM_ENABLE
(package wide)can not be enabled after resumed, due to
intel_pstate_hwp_enable() will only be invoked on AP's online
process after resumed - if there's no AP online, the HWP remains
disabled after resumed (BIOS has disabled it in S3). Then if
there comes a _PPC change notification which touches HWP register
during this stage, the warning is triggered.

Since we don't call acpi_processor_register_performance() when
HWP is enabled, the pr->performance will be NULL. When this is
NULL we don't need to do _PPC change notification.

The acpi_get_bus_status wrapper for acpi_bus_get_status_handle has some
code to handle certain device quirks, in some cases we also need this
quirk handling for the initial _STA call.

Specifically on some devices calling _STA before all _DEP dependencies
are met results in errors like these:

[    0.123579] ACPI Error: No handler for Region [ECRM] (00000000ba9edc4c)

               \_SB.I2C1.BAT1._STA, AE_NOT_EXIST (20170831/psparse-550)

acpi_get_bus_status already has code to avoid this, so by using it we
also silence these errors from the initial _STA call.

Note that in order for the acpi_get_bus_status handling for this to work,
we initialize dep_unmet to 1 until acpi_device_dep_initialize gets called,
this means that battery devices will be instantiated with an initial
status of 0. This is not a problem, acpi_bus_attach will get called soon
after the instantiation anyways and it will update the status as first
point of order.

The battery code uses acpi_device->dep_unmet to check for unmet deps and
if there are unmet deps it does not bind to the device to avoid errors
about missing OpRegions when calling ACPI methods on the device.

The missing OpRegions when there are unmet deps problem also applies to
the _STA method of some battery devices and calling it too early results
in errors like these:

Centaur CPU has a constant frequency TSC and that TSC does not stop in
C-States. But because the corresponding TSC feature flags are not set for
that CPU, the TSC is treated as not constant frequency and assumed to stop
in C-States, which makes it an unreliable and unusable clock source.

Setting those flags tells the kernel that the TSC is usable, so it will
select it over HPET.  The effect of this is that reading time stamps (from
kernel or user space) will be faster and more efficent.

acpi_lpss_create_device() skips handling LPSS devices which do not have
a mmio resources in their resource list (typically these devices are
disabled by the firmware). But since the LPSS code does not bind to the
device, acpi_bus_attach() ends up still creating a platform device for
it and the regular platform_driver for the ACPI HID still tries to bind
to it.

This happens e.g. on some boards which do not use the pwm-controller
and have an empty or invalid resource-table for it. Currently this causes
these error messages to get logged:

[    3.281966] pwm-lpss 80862288:00: invalid resource
[    3.287098] pwm-lpss: probe of 80862288:00 failed with error -22

This commit stops the undesirable creation of a platform_device for
disabled LPSS devices by setting pnp.type.platform_id to 0. Note that
acpi_scan_attach_handler() also sets pnp.type.platform_id to 0 when there
is a matching handler for the device and that handler has no attach
callback, so we simply behave as a handler without an attach function
in this case.

Some systems don't support the ACPI_LPS0_ENTRY and ACPI_LPS0_EXIT
functions in their Low Power S0 Idle _DSM, but still expect EC
events to be processed in the suspend-to-idle state for power button
wakeup (among other things) to work.  Surface Pro3 turns out to be
one of them.

Fortunately, it still provides Low Power S0 Idle _DSM with the screen
on/off functions supported, so modify the ACPI suspend-to-idle to use
the Low Power S0 Idle code path for all systems supporting the
ACPI_LPS0_ENTRY and ACPI_LPS0_EXIT or the ACPI_LPS0_SCREEN_OFF and
ACPI_LPS0_SCREEN_ON functions in their Low Power S0 Idle _DSM.

Potentially, that will cause more systems to use suspend-to-idle by
default, so some future corrections may be necessary if it leads
to issues, but let it remain more straightforward for now.

Sometimes the user wants to have device name of the match rather than
just checking if device present or not. To make life easier for such
users introduce acpi_dev_get_first_match_name() helper based on code
for acpi_dev_present().

For example, GPIO driver for Intel Merrifield needs to know the device
name of pin control to be able to apply GPIO mapping table to the proper
device.

To be more consistent with the purpose rename

  struct acpi_dev_present_info  -> struct acpi_dev_match_info
  acpi_dev_present_cb()         -> acpi_dev_match_cb()

in the utils.c file.

Convert DEVICE_ATTR uses to DEVICE_ATTR_RO where possible.

Done with perl script:

$ git grep -w --name-only DEVICE_ATTR | \
  xargs perl -i -e 'local $/; while (<>) { s/\bDEVICE_ATTR\s*\(\s*(\w+)\s*,\s*\(?(?:\s*S_IRUGO\s*|\s*0444\s*)\)?\s*,\s*\1_show\s*,\s*NULL\s*\)/DEVICE_ATTR_RO(\1)/g; print;}'

ACPICA commit 83f3375d6dcb3af812c91aaf47abcac9fc330527

This adds a semi-colon at the end of a macro call so that it can be
processed correctly with source code formatting tools.

ACPICA commit c75af007d35c0afe8791ac39b7749c7442f49912

The %*s format specifier prints a string with a width indicated by an integer.

In the case of acpi_os_printf() ("%*s", acpi_gbl_nesting_level, " "),
a single space is printed to the console when acpi_gbl_nesting_level
is 0 or 1. This change increments acpi_gbl_nesting_level so that there
is one space printed when acpi_gbl_nesting_level is 0 and two spaces
printed when acpi_gbl_nesting_level is 1.
