Currently the return value of 'sub_driver->init' is not checked. If
sparse_keymap_setup() called in the init function fails, 'generic_
inputdev' is freed, then it will lead a UAF when using it in generic_
acpi_laptop_init(). Fix it by checking the return value and setting
generic_inputdev to NULL after free, so as to avoid double free it.
The error code in generic_subdriver_init() is always negative, so the
return of generic_subdriver_init() can be simplified.

Some laptops don't support SW_LID, but still have backlight control,
move backlight resuming before SW_LID event handling so as to avoid

commit b0c07116c8 ("platform/x86: amd-pmc: Avoid reading SMU version at
probe time") adjusted the behavior for amd-pmc to avoid reading the SMU
version at startup but rather on first use to improve boot time.
However the SMU version is also used to decide whether to place a timer
based wakeup in the OS_HINT message. If the idlemask hasn't been read
before this message was sent then the SMU version will not have been
cached.
Ensure the SMU version has been read before deciding whether or not to
run this codepath.

It is observed that when thinkpad_acpi driver loads before amd-pmf
driver, thinkpad_acpi driver sends the AMT "on" event and the request
immediately will be part of the PMF BIOS "pending requests".
With the current amd-pmf code, as soon as the amd-pmf driver gets
probed, it calls apmf_acpi_init() where the notify handler will be
installed. Handler callback would call amd_pmf_handle_amt() where the
amd_pmf_set_automode() shall update the auto-mode thermals.
In this case, the auto-mode config_store shall have "zeros", as the
auto mode init gets called during the later stage.
To fix this, change the order of the acpi notifer install and call it
after the auto mode initialization is done.

CnQF (a.k.a Cool and Quiet Framework) extends the static slider concept.
PMF dynamically manages system power limits and fan policy based on system
power trends which is representative of workload trend.
Static slider and CnQF controls are mutually exclusive for system power
budget adjustments. CnQF supports configurable number of modes which can
be unique for AC and DC. Every mode is representative of a system state
characterized by unique steady state and boost behavior.
OEMs can configure the different modes/system states and how the
transition to a mode happens. Whether to have CnQF manage system power
budget dynamically in AC or DC or both is also configurable. Mode changes
due to CnQF don't result in slider position change.
The default OEM values are obtained after evaluating the PMF ACPI function
idx 11 & 12 for AC and DC respectively. Whether to turn ON/OFF by default
is guided by a "flag" passed by the OEM BIOS.

Some Toshibas have a broken acpi-video interface for brightness control, so
far these have been using a special workaround in drivers/acpi/acpi_video.c
which gets activated by the disable_backlight_sysfs_if module-param/quirks.
The recent x86/acpi backlight refactoring has broken this workaround:
1. This workaround relies on acpi_video_get_backlight_type() returning
acpi_video so that the acpi_video code actually runs; and
2. this relies on the actual native GPU driver to offer the sysfs
backlight interface to userspace.
After the refactor this breaks since the native driver will no
longer register its backlight-device if acpi_video_get_backlight_type()
does not return native and making it return native breaks 1.
Keeping the acpi_video backlight handling on resume active, while not
using it to set the brightness, is necessary because it does a _BCM
call on resume which is necessary to turn the panel back on on resume.
Looking at the DSDT shows that this _BCM call results in a Toshiba
HCI_SET HCI_LCD_BRIGHTNESS call, which turns the panel back on.
This commit makes toshiba_acpi do a HCI_SET HCI_PANEL_POWER_ON call
on resume on the affected models, so that the (now broken)
acpi_video disable_backlight_sysfs_if workaround will no longer
be necessary.
Note this uses HCI_PANEL_POWER_ON instead of HCI_LCD_BRIGHTNESS
to avoid changing the configured brightness level.
