6396bb2215 treewide: kzalloc() -> kcalloc()
The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:

        kzalloc(a * b, gfp)

with:
        kcalloc(a * b, gfp)

as well as handling cases of:

        kzalloc(a * b * c, gfp)

with:

        kzalloc(array3_size(a, b, c), gfp)

as it's slightly less ugly than:

        kzalloc_array(array_size(a, b), c, gfp)

This does, however, attempt to ignore constant size factors like:

        kzalloc(4 * 1024, gfp)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

e6a7379fcb platform/x86: dell-laptop: Fix keyboard backlight timeout on XPS 13 9370
The XPS 13 9370 doesn't expose the necessary KBD_LED_AC_TOKEN in
the BIOS, so the driver thinks it cannot adjust the AC keyboard
backlight timeout. This patch adds a quirk to fix this until
Dell adds the missing token to the BIOS.

64b824649b platform/x86: dell-wmi: Ignore new rfkill and fn-lock events
There are two new events generated by dell-wmi, rfkill and fn-lock, from
Dell Systems.

When Fn-lock hotkey gets pressed to switch to function mode:
[85951.591542] dell_wmi: Unknown key with type 0x0010 and code 0xe035
pressed
[85951.591546] dell_wmi: Unknown key with type 0x0010 and code 0x0000
pressed

When Fn-lock hotkey gets pressed to switch to multimedia mode:
[85956.667686] dell_wmi: Unknown key with type 0x0010 and code 0xe035
pressed
[85956.667690] dell_wmi: Unknown key with type 0x0010 and code 0x0001
pressed

When radio hotkey gets pressed:
[85974.430220] dell_wmi: Unknown key with type 0x0010 and code 0xe008
pressed

These events are for notification purpose, so we can ignore them.

This patch is tested on XPS 9370.

cbf7ff8cdb platform/mellanox: Add new ODM system types to mlx-platform
Add new ODM system types, matched according to DMI_BOARD_NAME. The
supported ODM Ids are: VMOD0001, VMOD0002, VMOD0003, VMOD0004, VMOD0005.
Patch does not introduce new systems, but allows to ODM companies to set
DMI_BOARD_VENDOR and DMI_PRODUCT_NAME on their own. It assumes that ODM
company can't change DMI_BOARD_NAME.

This commit adds the necessary device-properties to make the touchscreen

Note that we already have an entry for the Point of View mobii
TAB-P800W (v2.1), that version uses a different digitizer and different
firmware, so the v2.0 version needs its own entry.

Right now it's possible to set dell laptop to compile in but this
causes dell-smbios to compile in which breaks if dcdbas is a module.

Dell laptop shouldn't select dell-smbios anymore, but depend on it.

This leads to a NULL pointer derefence when the led device is

The method struct vga_switcheroo_handler::get_client_id() is defined
as returning an 'enum vga_switcheroo_client_id' but the implementation
in this driver, gmux_get_client_id(), returns an 'int'.

Fix this by returning 'enum vga_switcheroo_client_id' in this driver too.

8fddfb39a4 platform: x86: intel_scu_ipc: Replace mdelay with usleep_range in intel_scu_ipc_i2c_cntrl
intel_scu_ipc_i2c_cntrl() calls mutex_lock(), which indicates
this function is not called in atomic context.

Despite never getting called from atomic context,
intel_scu_ipc_i2c_cntrl() calls mdelay to busily wait.
This is not necessary and can be replaced with usleep_range to
avoid busy waiting.

This is found by a static analysis tool named DCNS written by myself.
And I also manually check it.

de15b94f87 platform/x86: fujitsu-laptop: Simplify soft key handling
The hardcoded BIT(X) used in the soft key handling can be confusing and
prone to errors.

Instead, use the status FLAG_* defines for the sparse keymap index.
Rather than check for each known bit, use a bitmask to filter for all
known soft keys, and use the for_each_set_bit iterator.

a7726f6b61 platform-drivers-x86 for v4.17-1
Dell SMBIOS driver fixed against memory leaks.
 
 The fujitsu-laptop driver is cleaned up and now supports hotkeys for
 Lifebook U7x7 models. Besides that the typo introduced by one of
 previous clean up series has been fixed.
 
 Specific to x86-based laptops HID device now supports
 KEY_ROTATE_LOCK_TOGGLE event which is emitted, for example,
 by Wacom MobileStudio Pro 13.
 
 Turbo MAX 3 technology is enabled for the rest of platforms that support
 Hardware-P-States feature which have core priority described by
 ACPI CPPC table.
 
 Mellanox on x86 gets better support of I2C bus in use including support
 of hotpluggable ones.
 
 Silead touchscreen is enabled on two tablet models, i.e Yours Y8W81 and
 I.T.Works TW701.
 
 From now on the second fan on Thinkpad P50 is supported.
 
 The topstar-laptop driver is reworked to support new models, in
 particular Topstar U931.
 
 Some of the changes had been already applied during v4.16 cycle and thus
 have a duplication here:
 
 - 027d50ccd6 platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's

Pull x86 platform driver updates from Andy Shevchenko:

 - Dell SMBIOS driver fixed against memory leaks.

 - The fujitsu-laptop driver is cleaned up and now supports hotkeys for
   Lifebook U7x7 models. Besides that the typo introduced by one of
   previous clean up series has been fixed.

 - Specific to x86-based laptops HID device now supports
   KEY_ROTATE_LOCK_TOGGLE event which is emitted, for example, by Wacom
   MobileStudio Pro 13.

 - Turbo MAX 3 technology is enabled for the rest of platforms that
   support Hardware-P-States feature which have core priority described
   by ACPI CPPC table.

 - Mellanox on x86 gets better support of I2C bus in use including
   support of hotpluggable ones.

 - Silead touchscreen is enabled on two tablet models, i.e Yours Y8W81
   and I.T.Works TW701.

 - From now on the second fan on Thinkpad P50 is supported.

 - The topstar-laptop driver is reworked to support new models, in
   particular Topstar U931.

ac9053d2dc USB/PHY patches for 4.17-rc1
Here is the big set of USB and PHY driver patches for 4.17-rc1.
 
 Lots of USB typeC work happened this round, with code moving from the
 staging directory into the "real" part of the kernel, as well as new
 infrastructure being added to be able to handle the different types of
 "roles" that typeC requires.
 
 There is also the normal huge set of USB gadget controller and driver
 updates, along with XHCI changes, and a raft of other tiny fixes all
 over the USB tree.  And the PHY driver updates are merged in here as
 well as they interacted with the USB drivers in some places.
 
 All of these have been in linux-next for a while with no reported
 issues.

a986c75a7d platform/x86: thinkpad_acpi: Add 2nd Fan Support for Thinkpad P50
The Thinkpad P50 has 2 fans. Add the 2FAN quirk so the tpacpi driver
properly reports both fan speeds.
Because the P50 doesn't report the version of its EC controller,
we need to identify it by BIOS version (N1).

We're freeing "value_name" which is NULL, so that's a no-op, but we
intended to free "location_name" instead.  And then we don't free the
names in token_location_attrs[0] and token_value_attrs[0].

Add an entry with touchscreen info for the Yours Y8W81 8" tablet.

This tablet has the same case and mostly the same internals as the Chuwi
Vi8. Both seem to be from an ODM called inet-tek. Both are labelled:
"INET-I86M-REVxx" on the PCB, with the Chuwi Vi8 being REV03 (and having
an ALC5640 audio codec) and the Yours Y8W81 being REV21 (and having an
ALC5651 audio codec). The wifi, accelerometer and touchscreen are
identical on both.

ef0f62264b platform/x86: mlx-platform: Add physical bus number auto detection
mlx-platform does not provide a bus number to i2c-mlxcpld, assuming it
is always one. On some x86 systems, other i2c drivers may probe before
i2c-mlxcpld, causing bus one to be busy.

Make mlx-platform determine which adapter number is free prior to
activating i2c-mlxpld, adjusting the mux base numbers accordingly.
Update the mlxreg-hotplug pdata similarly.

This adds an explicit mlx-platform build dependency on I2C, update the
Kconfig accordingly. Add the missing REGMAP dependency while we're at
it.

d726f6b199 platform/x86: mlx-platform: Add deffered bus functionality
mlx-platform activates i2c-mux-reg, which creates buses needed by
mlxreg-hotplug. If the mlxreg-hotplug probe runs before the i2c-mux-reg
probe completes, it may attempt to connect a device to an adapter number
that has not been created yet, and fail.

Make mlx-platform driver record the highest bus number in mlxreg-hotplug
platform data and defer mlxreg-hotplug probe until all the buses are
created.
