2024-11-12intel-hid: fix volume buttons on Thinkpad X12 Detachable Tablet Gen 1Cole Stowell
Volume buttons on Lenovo Thinkpad X12 Detachable Tablet Gen 1 did not send any input events when pressed. When loading intel-hid with the 5 Button Array explicitly enabled, the buttons functioned normally. Adds the X12 Detachable Tablet Gen 1 to the `button_array_table`. However, the driver is unable to call INTEL_HID_DSM_BTNE_FN and prints the warning "failed to set button capability" when attempting to enable or disable the 5 Button Array. The warning should be harmless and adding more special handling to avoid it is not worth it.

2024-10-17platform/x86: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/platform/x86/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.

2024-04-08platform/x86/intel/hid: Don't wake on 5-button releasesDavid McFarland
If, for example, the power button is configured to suspend, holding it and releasing it after the machine has suspended, will wake the machine. Also on some machines, power button release events are sent during hibernation, even if the button wasn't used to hibernate the machine. This causes hibernation to be aborted.

2023-07-25platform/x86/intel/hid: Add HP Dragonfly G2 to VGBS DMI quirksMaxim Mikityanskiy
HP Elite Dragonfly G2 (a convertible laptop/tablet) has a reliable VGBS method. If VGBS is not called on boot, the firmware sends an initial 0xcd event shortly after calling the BTNL method, but only if the device is booted in the laptop mode. However, if the device is booted in the tablet mode and VGBS is not called, there is no initial 0xcc event, and the input device for SW_TABLET_MODE is not registered up until the user turns the device into the laptop mode. Call VGBS on boot on this device to get the initial state of SW_TABLET_MODE in a reliable way. Tested with BIOS 1.13.1.

2023-07-25platform/x86: intel: hid: Always call BTNL ACPI methodHans de Goede
On a HP Elite Dragonfly G2 the 0xcc and 0xcd events for SW_TABLET_MODE are only send after the BTNL ACPI method has been called. Likely more devices need this, so make the BTNL ACPI method unconditional instead of only doing it on devices with a 5 button array. Note this also makes the intel_button_array_enable() call in probe() unconditional, that function does its own priv->array check. This makes the intel_button_array_enable() call in probe() consistent with the calls done on suspend/resume which also rely on the priv->array check inside the function.

2023-03-07platform/x86: intel: hid: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

SW_TABLET_MODE reporting The driver has DMI-quirk tables for force-enabling 5 button array support and for 2 different ways of enabling SW_TABLET_MODE reporting. Add module parameters to allow user to enable the driver behavior currently only available through DMI quirks. This is useful for users to test this in bug-reports and for users to use as a workaround while new DMI quirks find their way upstream.
