<id>urn:sha1:e64cd7a033436300a1e4aee982d6530bd708f465</id>
<content type='text'>
commit f3e4f3fc8ee9729c4b1b27a478c68b713df53c0c upstream.

The AML code implementing the WMI methods creates a variable length
field to hold the input data we pass like this:

        CreateDWordField (Arg1, 0x0C, DSZI)
        Local5 = DSZI /* \HWMC.DSZI */
        CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN)

If we pass 0 as bios_args.datasize argument then (Local5 * 0x08)
is 0 which results in these errors:

[   71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133)
[   71.973332] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)
[   71.973413] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529)

And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands
like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for
read commands where extra input is needed to specify exactly what to read.

So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected
output as insize to hp_wmi_perform_query(), as we are already doing for all
other HPWMI_READ commands we send. Doing so fixes these errors.

<title>platform/x86: hp-wmi: Fix ACPI errors caused by too small buffer</title>

<id>urn:sha1:5227ac4ddacdde511f10679a0b55797b8a2ecfd8</id>
<content type='text'>
commit 16245db1489cd9aa579506f64afeeeb13d825a93 upstream.

The HP WMI calls may take up to 128 bytes of data as input, and
the AML methods implementing the WMI calls, declare a couple of fields for
accessing input in different sizes, specifycally the HWMC method contains:

        CreateField (Arg1, 0x80, 0x0400, D128)

Even though we do not use any of the WMI command-types which need a buffer
of this size, the APCI interpreter still tries to create it as it is
declared in generoc code at the top of the HWMC method which runs before
the code looks at which command-type is requested.

This results in many of these errors on many different HP laptop models:

[   14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236)
[   14.459268] ACPI Error: Method parse/execution failed [\HWMC] (Node ffff8edcc61507f8), AE_AML_BUFFER_LIMIT (20170303/psparse-543)
[   14.459279] ACPI Error: Method parse/execution failed [\_SB.WMID.WMAA] (Node ffff8edcc61523c0), AE_AML_BUFFER_LIMIT (20170303/psparse-543)

This commit increases the size of the data element of the bios_args struct
to 128 bytes fixing these errors.

<title>platform/x86: i2c-multi-instantiate: Fail the probe if no IRQ provided</title>

<content type='text'>
For APIC case of interrupt we don't fail a -&gt;probe() of the driver,
which makes kernel to print a lot of warnings from the children.

We have two options here:
- switch to platform_get_irq_optional(), though it won't stop children
  to be probed and failed
- fail the -&gt;probe() of i2c-multi-instantiate

Since the in reality we never had devices in the wild where IRQ resource
is optional, the latter solution suits the best.

Since the commit

  7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")

the platform_get_irq() started issuing an error message which is not
what we want here.

Switch to platform_get_irq_optional() to have only warning message
provided by the driver.

When naming the new devices, instead of using the ACPI ID in
the name as base, using the parent device's name. That makes
it possible to support multiple multi-instance i2c devices
of the same type in the same system.

This fixes an issue seen on some Intel Kaby Lake based
boards:

sysfs: cannot create duplicate filename '/devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-INT3515-tps6598x.0'

The SIMATIC IPC277E uses the PMC clock for on-board components
and gets stuck during boot if the clock is disabled. Therefore,
add this device to the critical systems list.

Tested on SIMATIC IPC277E.

Pull input updates from Dmitry Torokhov:

 - input core allows hardware drivers to specify a [more precise]
   timestamp (normally taken in top half) to better track velocity of
   contacts

 - input_dev instances now support "polling" mode so that drivers could
   use the same object for polled and interrupt-driven operation. The
   plan is to convert existing drivers and retire input_polled_dev API

 - a new driver for the FlySky FS-iA6B RC receiver

 - a refresh of BU21013 touchpad driver

 - w90x900 keyboard and touchpad drivers are removed as the platform is
   gone

 - assorted fixes
