The ACPI_HANDLE() macro is a wrapper arond the ACPI_COMPANION()
macro and the ACPI handle produced by the former comes from the
ACPI device object produced by the latter, so it is way more
straightforward to evaluate the latter directly instead of passing
the handle produced by the former to acpi_bus_get_device().
Modify ideapad_acpi_add() accordingly (no intentional functional
impact).

VPC event bit 10 gets set on a Yoga 300-11IBR when the EC believes that the
device has changed between laptop/tent/stand/tablet mode.
The EC relies on getting angle info from 2 accelerometers through a special
windows service calling a DSM on the DUAL250E ACPI-device. Linux does not
do this, making the laptop/tent/stand/tablet mode info unreliable.
Ignore VPC event bit 10 to avoid the warnings triggered by the default case
in ideapad_acpi_notify().
Note that the plan for Linux is to have iio-sensor-proxy read the 2
accelerometers and have it provide info about which mode 360° hinges

Consumers can differentiate an error from a successful read much more
easily if the read() call fails with an appropriate errno instead of
returning a magic string like "-1". This introduces an ABI change, but
not many users are expected to be relying on the previous behavior,
and this change makes this module conforming to the standard behavior
that sysfs attribute show/store callbacks return an appropriate
errno in case of failure. Thus the ABI breakage is deemed justified.

Pull x86 platform driver updates from Andy Shevchenko:
"Gathered a bunch of x86 platform driver changes. It's rather big,
since includes two big refactors and completely new driver:
- ASUS WMI driver got a big refactoring in order to support the TUF
Gaming laptops. Besides that, the regression with backlight being
permanently off on various EeePC laptops has been fixed.
- Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
X axis being inverted. This has been fixed.
- Intel PMC core driver has been extended to be ACPI enumerated if
the DSDT provides device with _HID "INT33A1". This allows to
convert the driver to be pure platform and support new hardware
purely based on ACPI DSDT.
- From now on the Intel Speed Select Technology is supported thru a
corresponding driver. This driver provides an access to the
features of the ISST, such as Performance Profile, Core Power, Base
frequency and Turbo Frequency.
- Mellanox platform drivers has been refactored and now extended to
support more systems, including new coming ones.
- The OLPC XO-1.75 platform is now supported.
- CB4063 Beckhoff Automation board is using PMC clocks, provided via
pmc_atom driver, for ethernet controllers in a way that they can't
be managed by the clock driver. The quirk has been extended to
cover this case.
- Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
the information of Chuwi Hi10 Air has been fixed to cover more
models based on the same platform.
- Xiaomi notebooks have WMI interface enabled. Thus, the driver to
support it has been provided. It required some extension of the
generic WMI library, which allows to propagate opaque context to
the ->probe() of the individual drivers.
This release includes debugfs clean up from Greg KH for several
drivers that drop return code check and make debugfs absence or
failure non-fatal.
Also miscellaneous fixes here and there, mostly for Acer WMI and
various Intel drivers"

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.

But DMI_BOARD_NAME does not match 80WW on Lenovo RESCUER R720-15IKBN,
thus cause Wireless LAN still be hard blocked.

~$ cat /sys/class/dmi/id/sys_vendor

Provence-5R3
~$ cat /sys/class/dmi/id/product_name

So on Lenovo RESCUER R720-15IKBN:
DMI_SYS_VENDOR should match "LENOVO",
DMI_BOARD_NAME should match "Provence-5R3",
DMI_PRODUCT_NAME should match "80WW",
DMI_PRODUCT_VERSION should match "Lenovo R720-15IKBN".
Fix it, and in according with other entries in no_hw_rfkill_list,
use DMI_PRODUCT_VERSION instead of DMI_BOARD_NAME.
