BIOS/ACPI on devices with WMI interface version 0 does not clear buffer
before filling it. So next time when BIOS/ACPI send WMI event which is
smaller as previous then it contains garbage in buffer from previous event.
BIOS/ACPI on devices with WMI interface version 1 clears buffer and
sometimes send more events in buffer at one call.
Since commit 83fc44c32ad8 ("dell-wmi: Update code for processing WMI
events") dell-wmi process all events in buffer (and not just first).
To prevent reading garbage from the buffer we process only the first
event on devices with WMI interface version 0.

After examining existing DSDT ACPI tables of more laptops and looking
into Dell WMI document mentioned in ML dicussion archived at
http://www.spinics.net/lists/platform-driver-x86/msg07220.html we will
parse and check WMI descriptor if contains expected data. It is because
WMI descriptor contains interface version number and it is needed to
know in next commit.

Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
separate ACPI device for notifications from the airplane mode hotkey.
This device is called "Wireless Radio Control" in Asus websites and ASHS
in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
above.
For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
query 0x0B is started in the Embedded Controller, and all this query does
is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):
Scope (_SB.PCI0.SBRG.EC0)
{
(...)
Method (_Q0B, 0, NotSerialized) // _Qxx: EC Query
{
If ((MSOS () >= OSW8))
{
Notify (ASHS, 0x88) // Device-Specific
}
Else
{
(...)
}
}
}

If DMI lists a hotkey that we don't recognize, log and ignore it
instead of trying to map it to keycode 0. I haven't seen this happen,
but it will help maintain the key map in the future and it will help
avoid sending bogus events.
This also improves the message that we log when we get an unknown key
event.

Certain Toshiba models with the second generation keyboard backlight
(type 2) do not generate the keyboard backlight changed event (0x92),
and thus, the sysfs entries are never being updated.
This patch adds a workquee and a global boolean variable to address
the issue.
For those models that do generate the event, the sysfs entries are
being updated via the *notify function and the boolean is set to
true to avoid a second call to update the entries.
For those models that do not generate the event, the workquee is
used to update the sysfs entries and also to emulate the event via
netlink, to make userspace aware of such change.

If menu_select() cannot find a suitable state to return, it will
return the state index stored in data->last_state_idx. This
means that it is pointless to look at the states whose indices
are less than or equal to data->last_state_idx in the main loop,
so don't do that.
Given that those checks are done on every idle state selection, this
change can save quite a bit of completely unnecessary overhead.

After commit 9c4b2867ed7c (cpuidle: menu: Fix menu_select() for
CPUIDLE_DRIVER_STATE_START == 0) it is clear that menu_select()
cannot return negative values. Moreover, ladder_select_state()
will never return a negative value too, so make find_deepest_state()
return non-negative values too and drop the default_idle_call()
fallback from call_cpuidle().
This eliminates one branch from the idle loop and makes the governors
and find_deepest_state() handle the case when all states have been
disabled from sysfs consistently.

The Kconfig for this support is currently:
config IDEPCI_PCIBUS_ORDER
bool "Probe IDE PCI devices in the PCI bus order (DEPRECATED)"
...meaning that it currently is not being built as a module by anyone.
Lets change the initcall to be the equivalent device_initcall, so that
when reading the driver code, there is no doubt it is builtin-only.
Unlike other similar changes, we leave the module.h header to be
included since this code interacts with other drivers and needs to
know what a struct module is.

Back in the day we used to just say this code was root only so it was
ok that the bounds checking was sloppy. These days it annoys static
checkers so we fix it.
In the original code "c > INT_MAX" was never true since "c" was an int.
I am not sure what was intended so I left it alone. But because I made
"c" unsigned it means we don't have a warning any more.
The second warning is that we cap "i" but allow negatives leading to an
underflow of the ide_disks_chs[] array. The third set of warnings is
because these values come from the user and we cap most of the upper
bounds but allow negative values. Negative cylinders doesn't make
sense.

at803x currently automatically enables the RGMII TX clock delay when the
phy interface mode is PHY_INTERFACE_MODE_RGMII_TXID. The same should be
done when PHY_INTERFACE_MODE_RGMII_ID is specified.
Use a similar logic to enable the RGMII RX clock delay as well.
at803x_context_{save,restore} were not touched because these are only
used on AR8030 which is a RMII phy (RGMII clock delays are irrelevant).

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio
Pull GPIO updates from Linus Walleij:
"Here is the bulk of GPIO changes for v4.5.
Notably there are big refactorings mostly by myself, aimed at getting
the gpio_chip into a shape that makes me believe I can proceed to
preserve state for a proper userspace ABI (character device) that has
already been proposed once, but resulted in the feedback that I need
to go back and restructure stuff. So I've been restructuring stuff.
On the way I ran into brokenness (return code from the get_value()
callback) and had to fix it. Also, refactored generic GPIO to be
simpler.
Some of that is still waiting to trickle down from the subsystems all
over the kernel that provide random gpio_chips, I've touched every
single GPIO driver in the kernel now, oh man I didn't know I was
responsible for so much...
Apart from that we're churning along as usual.
I took some effort to test and retest so it should merge nicely and we
shook out a couple of bugs in -next.
Infrastructural changes:
- In struct gpio_chip, rename the .dev node to .parent to better
reflect the fact that this is not the GPIO struct device
abstraction. We will add that soon so this would be totallt
confusing.
- It was noted that the driver .get_value() callbacks was sometimes
reporting negative -ERR values to the gpiolib core, expecting them
to be propagated to consumer gpiod_get_value() and gpio_get_value()
calls. This was not happening, so as there was a mess of drivers
returning negative errors and some returning "anything else than
zero" to indicate that a line was active. As some would have bit
31 set to indicate "line active" it clashed with negative error
codes. This is fixed by the largeish series clamping values in all
drivers with !!value to [0,1] and then augmenting the code to
propagate error codes to consumers. (Includes some ACKed patches
in other subsystems.)
- Add a void *data pointer to struct gpio_chip. The container_of()
design pattern is indeed very nice, but we want to reform the
struct gpio_chip to be a non-volative, stateless business, and keep
states internal to the gpiolib to be able to hold on to the state
when adding a proper userspace ABI (character device) further down
the road. To achieve this, drivers need a handle at the internal
state that is not dependent on their struct gpio_chip() so we add
gpiochip_add_data() and gpiochip_get_data() following the pattern
of many other subsystems. All the "use gpiochip data pointer"
patches transforms drivers to this scheme.
- The Generic GPIO chip header has been merged into the general
<linux/gpio/driver.h> header, and the custom header for that
removed. Instead of having a separate mm_gpio_chip struct for
these generic drivers, merge that into struct gpio_chip,
simplifying the code and removing the need for separate and
confusing includes.
Misc improvements:
- Stabilize the way GPIOs are looked up from the ACPI legacy
specification.
- Incremental driver features for PXA, PCA953X, Lantiq (patches from
the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48
New drivers:
- Add a GPIO chip to the ALSA SoC AC97 driver.
- Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir,
but the branch is merged here too to account for infrastructural
changes).
- The sx150x driver now supports the sx1502"

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai:
"We've had quite busy weeks in this cycle. Looking at ALSA core, the
significant changes are a few fixes wrt timer and sequencer ioctls
that have been revealed by fuzzer recently. Other than that, ASoC
core got a few updates about DAI link handling, but these are rather
straightforward refactoring.
In drivers scene, ASoC received quite lots of new drivers in addition
to bunch of updates for still ongoing Intel Skylake support and
topology API. HD-audio gained a new HDMI/DP hotplug notification via
component. FireWire got a pile of code refactoring/updates with
SCS.1x driver integration.
More highlights are shown below.
[ NOTE: this contains also many commits for DRM. This is due to the
pull of drm stable branch into sound tree, as the base of i915 audio
component work for HD-audio. The highlights below don't contain
these DRM changes, as these are supposed to be pulled via drm tree
in anyway sooner or later. ]
Core:
- Handful fixes to harden ALSA timer and sequencer ioctls against
races reported by syzkaller fuzzer
- Irq description string can be unique to each card; only for
HD-audio for now
ASoC:
- Conversion of the array of DAI links to a list for supporting
dynamically adding and removing DAI links
- Topology API enhancements to make everything more component based
and being able to specify PCM links via topology
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production; we really need to get to the
point where that can be done
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come
- Lots of new features and cleanups for the Renesas drivers
- ANC support for WM5110
- New drivers: Imagination Technologies IPs, Atmel class D speaker,
Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and
RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP
- Rename PCM1792a driver to be generic pcm179x
HD-Audio:
- Use audio component for i915 HDMI/DP hotplug handling
- On-demand binding with i915 driver
- bdl_pos_adj parameter adjustment for Baytrail controllers
- Enable power_save_node for CX20722; this shouldn't lead to
regression, hopefully
- Kabylake HDMI/DP codec support
- Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell
machines
- A few code refactoring
FireWire:
- Lots of code cleanup and refactoring
- Integrate the support of SCS.1x devices into snd-oxfw driver;
snd-scs1x driver is obsoleted
USB-audio:
- Fix possible NULL dereference at disconnection
- A regression fix for Native Instruments devices
Misc:
- A few code cleanups of fm801 driver"
