Since it works without problems on Windows I assume ASUS WMI driver for Win
never trying to get ALS state, and instead it is setting it by default to ON.
This patch will do the same. Turn ALS on by default.

The 98d610c373 patch was introduced since v4.11-rc1 that it causes
that the accelerometer input device will not be created on workable
machines because the HID string comparing logic is wrong.
And, the patch doesn't prevent that the accelerometer input device
be created on the machines that have no BST0001. That's because
the acpi_get_devices() returns success even it didn't find any
match device.
This patch fixed the HID string comparing logic of BST0001 device.
And, it also makes sure that the acpi_get_devices() returns
acpi_handle for BST0001.

Like other Lenovo models the IdeaPad V310-15ISK does not have an hw
rfkill switch. This results in hard-blocked radios after boot, resulting
in always blocked radios rendering them unusable.

iTCO_wdt driver need access to PMC_CFG GCR register to modify the
noreboot setting. Currently, this is done by passing PMC_CFG reg
address as memory resource to watchdog driver and allowing it directly
modify the PMC_CFG register. But currently PMC driver also has
requirement to memory map the entire GCR register space in this driver.
This causes mem request failure in watchdog driver. So this patch fixes
this issue by adding API to update noreboot flag and passes them
to watchdog driver via platform data.

According to Broxton APL spec, PMC MIMO resources for Global Control
Registers(GCR) are located at 4K(0x1000) offset from IPC base address.
In this driver, PLAT_RESOURCE_GCR_OFFSET macro defines the offset of GCR
region base address from IPC base address and its current value of
0x1008 is incorrect because it points to location for PMC_CFG register
and not the GCR base address itself.
GCR Base = IPC1 Base + 0x1000.
This patch fixes this offset issue.

When changing keyboard backlight state on new Dell laptops, firmware
expects a new timeout AC value filled in Set New State SMBIOS call.
Without it any change of keyboard backlight state on new Dell laptops
fails. And user can see following error message in dmesg:
dell_laptop: Setting old previous keyboard state failed
leds dell::kbd_backlight: Setting an LED's brightness failed (-6)
This patch adds support for retrieving current timeout AC values and also
updating them. Current timeout value in sysfs is displayed based on current
AC status, like current display brightness value.
Detection if Dell laptop supports or not new timeout AC settings is done by
checking existence of Keyboard Backlight with AC SMBIOS token (0x0451).

Use devm_led_classdev_register() for registering LED class devices in
order to simplify cleanup and remove LED-related fields with the
"_registered" suffix from struct fujitsu_laptop. This also fixes a
cleanup bug: with non-managed LED class devices, if e.g. two supported
LEDs are detected, the first one gets registered successfully but the
second one does not, acpi_fujitsu_laptop_add() will return an error, but
the successfully registered LED will never get unregistered.
Change the parent device for LED class devices to the FUJ02E3 ACPI
device due to this being the logically correct relationship as LED class
devices do not depend on any facility provided by the platform device
registered by fujitsu-laptop, which was their parent until now.
Each managed LED class device is automatically unregistered when the
last reference to its parent device is dropped. Taking the parent
change described above into account, LED class devices registered by
fujitsu-laptop will be unregistered after acpi_fujitsu_laptop_remove()
is called. During unregistration, LED brightness is reset to LED_OFF by
LED core, so do not set the acpi_handle field of struct fujitsu_laptop
to NULL inside acpi_fujitsu_laptop_remove() to prevent call_fext_func()
from generating errors upon module removal.
