platform/mellanox: mlxreg-hotplug: Revert "move to use request_irq by IRQF_NO_AUTOEN flag"

2021-06-04T20:03:13+00:00

It causes mlxreg-hotplug probing failure: request_threaded_irq()
 returns -EINVAL due to true value of condition:
((irqflags & IRQF_SHARED) && (irqflags & IRQF_NO_AUTOEN))
after flag "IRQF_NO_AUTOEN" has been added to:
	err = devm_request_irq(&pdev->dev, priv->irq,
			       mlxreg_hotplug_irq_handler, IRQF_TRIGGER_FALLING
			       | IRQF_SHARED | IRQF_NO_AUTOEN,
			       "mlxreg-hotplug", priv);

This reverts commit bee3ecfed0fc ("platform/mellanox: mlxreg-hotplug: move
to use request_irq by IRQF_NO_AUTOEN flag").

platform/surface: dtx: Add missing mutex_destroy() call in failure path

2021-06-04T20:00:27+00:00

When we fail to open the device file due to DTX being shut down, the
mutex is initialized but never destroyed. We are destroying it when
releasing the file, so add the missing call in the failure path as well.

platform/surface: aggregator: Fix event disable function

2021-06-03T11:07:34+00:00

Disabling events silently fails due to the wrong command ID being used.
Instead of the command ID for the disable call, the command ID for the
enable call was being used. This causes the disable call to enable the
event instead. As the event is already enabled when we call this
function, the EC silently drops this command and does nothing.

Use the correct command ID for disabling the event to fix this.

platform/x86: thinkpad_acpi: Add X1 Carbon Gen 9 second fan support

2021-05-27T09:23:57+00:00

The X1 Carbon Gen 9 uses two fans instead of one like the previous
generation. This adds support for the second fan. It has been tested
on my X1 Carbon Gen 9 (20XXS00100) and works fine.

platform/surface: aggregator_registry: Add support for 13" Intel Surface Laptop 4

2021-05-25T12:51:28+00:00

Add support for the 13" Intel version of the Surface Laptop 4.

Use the existing node group for the Surface Laptop 3 since the 15" AMD
version already shares its WSID HID with its predecessor and there don't
seem to be any significant differences with regards to SAM.

platform/x86: touchscreen_dmi: Add info for the Chuwi Hi10 Pro (CWI529) tablet

2021-05-20T12:11:03+00:00

Add touchscreen info for the Chuwi Hi10 Pro (CWI529) tablet. This includes
info for getting the firmware directly from the UEFI, so that the user does
not need to manually install the firmware in /lib/firmware/silead.

This change will make the touchscreen on these devices work OOTB,
without requiring any manual setup.

The intel_punit_ipc driver might be compiled as a module.
When udev handles the event of the devices appearing
the intel_punit_ipc module is missing.

Append MODULE_DEVICE_TABLE for ACPI case to fix the loading issue.

platform/x86: dell-smbios-wmi: Fix oops on rmmod dell_smbios

2021-05-19T13:59:47+00:00

init_dell_smbios_wmi() only registers the dell_smbios_wmi_driver on systems
where the Dell WMI interface is supported. While exit_dell_smbios_wmi()
unregisters it unconditionally, this leads to the following oops:

[  175.722921] ------------[ cut here ]------------
[  175.722925] Unexpected driver unregister!
[  175.722939] WARNING: CPU: 1 PID: 3630 at drivers/base/driver.c:194 driver_unregister+0x38/0x40

Make the unregister happen on the same condition the register happens
to fix this.
