Some of latest ASUS laptops support new fn-lock mode switching.
This commit detect whether if the fn-lock option is enabled in
BIOS setting, and toggle the fn-lock mode via a new WMI DEVID
0x00100023 when the corresponding notify code captured.
The ASUS fn-lock mode switch is activated by pressing Fn+Esc.
When on, keys F1 to F12 behave as applicable, with meanings
defined by the application being used at the time. When off,
F1 to F12 directly triggers hardware features, well known audio
volume up/down, brightness up/down...etc, which were triggered
by holding down Fn key and F-keys.
Because there's no way to retrieve the fn-lock mode via existing
WMI methods per ASUS spec, driver need to initialize and keep the
fn-lock mode by itself.

When the ideapad-laptop driver was first written it was written for laptops
which had a hardware rfkill switch. So when the first ideapad laptops
showed up without a hw rfkill switch and it turned out that in this case
the ideapad firmware interface would always report the wifi being hardware-
blocked, a DMI id list of models which lack a hw rfkill switch was started
(by yours truly). Things were done this way to avoid regressing existing
models with a hw rfkill switch. In hindsight this was a mistake.
Lenovo releases a lot of ideapad models every year and even the latest
models still use the "VPC2004" ACPI interface the ideapad-laptop driver
binds to. Having a hw rfkill switch is quite rare on modern hardware, so
all these new models need to be added to the no_hw_rfkill_list, leading
to a never ending game of whack a mole.
Worse the failure mode when not present on the list, is very bad. In this
case the ideapad-laptop driver will report the wifi as being hw-blocked,
at which points NetworkManager does not even try to use it and the user
ends up with non working wifi.
This leads to various Linux fora on the internet being filled with
wifi not working on ideapad laptops stories, which does not make Linux
look good.
The failure mode when we flip the default to assuming that a hw rfkill
switch is not present OTOH is quite benign. When we properly report the
wifi as being hw-blocked on ideapads which do have the hw-switch; and it
is in the wifi-off position, then at least when using NetworkManager +
GNOME3 the user will get a "wifi disabled in hardware" message when trying
to connect to the wifi from the UI. If OTOH we assume there is no hardware
rfkill switch, then the user will get an empty list for the list of
available networks. Although the empty list vs the "wifi disabled in
hardware" message is a regression, it is a very minor regression and it
can easily be fixed on a model by model basis by filling the new
hw_rfkill_list this commit introduces.
Therefor this commit removes the ever growing no_hw_rfkill_list, flipping
the default to assuming there is no hw rfkill switch and adding a new
hw_rfkill_list. Thereby fixing the wifi not working on all the current
ideapad and yoga models which are not on the list yet and also fixing it
for all future ideapad and yoga models using the "VPC2004" ACPI interface.
Note once this patch has been accepted upstream. I plan to write a blog
post asking for users of ideapads and yoga's with a hw rfkill switch to
step forward, so that we can populate the new hw_rfkill_list with the few
older yoga and ideapad models which actually have a hw rfkill switch.

It seems that the default case should return AE_CTRL_TERMINATE, instead
of falling through to case ACPI_RESOURCE_TYPE_END_TAG and returning AE_OK;
otherwise the line of code at the end of the function is unreachable and
makes no sense:
return AE_CTRL_TERMINATE;

Add a module parameter which when enabled, will check on resume, if the
last S0ix attempt was successful. If not, the driver would warn and provide
helpful debug information (which gets latched during the failed suspend
attempt) to debug the S0ix failure.
This information is very useful to debug S0ix failures. Specially since
the latched debug information will be lost (over-written) if the system
attempts to go into runtime (or imminent) S0ix again after that failed
suspend attempt.

The intel_pmc_ipc driver has a placeholder for all possible resources
that may have been provided by ACPI. Since there are few optional ones,
the driver still uses them and binds to wrong ranges in resource tree:
# grep intel_punit_ipc /proc/iomem
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
00000000-00000000 : intel_punit_ipc
This leads to issues with resource management during inserting and
removing modules, such as intel_pmc_ipc itself, which can't be inserted
anymore after first removal.
Count the actual resources provided and supply only them to the child device.
This is a real fix of the commit 8cc7fb4a6523
("intel_pmc_ipc: update acpi resource structure for Punit")
that also fixes a symptoms described in the commit 6cc8cbbc8868
("platform/x86: intel_punit_ipc: Fix resource ioremap warning")
that is going to be reverted afterwards.

Currently the kfree of output.pointer can be potentially freeing
an uninitalized pointer in the case where out_data is NULL. Fix this
by reworking the case where out_data is not-null to perform the
ACPI status check and also the kfree of outpoint.pointer in one block
and hence ensuring the pointer is only freed when it has been used.
Also replace the if (ptr != NULL) idiom with just if (ptr).

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v5.1 cycle:
Core changes:
- The big change this time around is the irqchip handling in the
qualcomm pin controllers, closely coupled with the gpiochip. This
rework, in a classic fall-between-the-chairs fashion has been
sidestepped for too long.
The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms
have been rewritten to use hierarchical irqchip. This creates the
base from which I intend to gradually pull support for hierarchical
irqchips into the gpiolib irqchip helpers to cut down on duplicate
code.
We have too many hacks in the kernel because people have been
working around the missing hierarchical irqchip for years, and once
it was there, noone understood it for a while. We are now slowly
adapting to using it.
This is why this pull requests include changes to MFD, SPMI,
IRQchip core and some ARM Device Trees pertaining to the Qualcomm
chip family. Since Qualcomm have so many chips and such large
deployments it is paramount that this platform gets this right, and
now it (hopefully) does.
- Core support for pull-up and pull-down configuration, also from the
device tree. When a simple GPIO chip supports an "off or on" pull-up
or pull-down resistor, we provide a way to set this up using
machine descriptors or device tree.
If more elaborate control of pull up/down (such as resistance shunt
setting) is required, drivers should be phased over to use pin
control. We do not yet provide a userspace ABI for this pull
up-down setting but I suspect the makers are going to ask for it
soon enough. PCA953x is the first user of this new API.
- The GPIO mockup driver has been revamped after some discussion
improving the IRQ simulator in the process.
The idea is to make it possible to use the mockup for both testing
and virtual prototyping, e.g. when you do not yet have a GPIO
expander to play with but really want to get something to develop
code around before hardware is available. It's neat. The blackbox
testing usecase is currently making its way into kernelci.
- ACPI GPIO core preserves non direction flags when updating flags.
- A new device core helper for devm_platform_ioremap_resource() is
funneled through the GPIO tree with Greg's ACK.
New drivers:
- TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O)
- Gateworks PLD GPIO driver (vaccumed up from OpenWrt)
- AMD G-Series PCH (Platform Controller Hub) GPIO driver.
- Fintek F81804 & F81966 subvariants.
- PCA953x now supports NXP PCAL6416.
Driver improvements:
- IRQ support on the Nintendo Wii (Hollywood) GPIO.
- get_direction() support for the MVEBU driver.
- Set the right output level on SAMA5D2.
- Drop the unused irq trigger setting on the Spreadtrum driver.
- Wakeup support for PCA953x.
- A slew of cleanups in the various Intel drivers"

The driver was newly introduced but the version that got merged
produces a harmless compiler warning:
drivers/platform/x86/pcengines-apuv2.c: In function 'apu_board_init':
drivers/platform/x86/pcengines-apuv2.c:211:6: error: unused variable 'rc' [-Werror=unused-variable]
Remove the evidently useless variable.

WMI drivers can if they have specified an array of struct wmi_device_id
use the MODULE_DEVICE_TABLE() macro to automatically generate the
appropriate MODULE_ALIAS() output. Thus avoiding to keep both the array
of struct wmi_device_id and the MODULE_ALIAS() declaration(s) in sync.
Change driver to use MODULE_DEVICE_TABLE() instead of MODULE_ALIAS().

In preparation for adding WMI support to MODULE_DEVICE_TABLE() move the
definition of struct wmi_device_id to mod_devicetable.h and inline
guid_string in the struct.
Changing guid_string to an inline char array changes the loop conditions
when looping over an array of struct wmi_device_id. Therefore update
wmi_dev_match()'s loop to check for an empty guid_string instead of a
NULL pointer.
