2021-03-23platform/x86: gpd pocket fan: Clean-up by using managed work initMatti Vaittinen1-11/+6
Few drivers implement remove call-back only for ensuring a delayed work gets cancelled prior driver removal. Clean-up these by switching to use devm_delayed_work_autocancel() instead. This change is compile-tested only. All testing is appreciated.

2021-03-21platform/x86: intel-vbtn: Stop reporting SW_DOCK eventsHans de Goede1-2/+10
Stop reporting SW_DOCK events because this breaks suspend-on-lid-close. SW_DOCK should only be reported for docking stations, but all the DSDTs in my DSDT collection which use the intel-vbtn code, always seem to use this for 2-in-1s / convertibles and set SW_DOCK=1 when in laptop-mode (in tandem with setting SW_TABLET_MODE=0). This causes userspace to think the laptop is docked to a port-replicator and to disable suspend-on-lid-close, which is undesirable. Map the dock events to KEY_IGNORE to avoid this broken SW_DOCK reporting. Note this may theoretically cause us to stop reporting SW_DOCK on some device where the 0xCA and 0xCB intel-vbtn events are actually used for reporting docking to a classic docking-station / port-replicator but I'm not aware of any such devices. Also the most important thing is that we only report SW_DOCK when it reliably reports being docked to a classic docking-station without any false positives, which clearly is not the case here. If there is a chance of reporting false positives then it is better to not report SW_DOCK at all.

On some system the WMI GUIDs used by dell-wmi-sysman are present but there are no enum type attributes, this causes init_bios_attributes() to return -ENODEV, after which sysman_init() does a "goto fail_create_group" and then calls release_attributes_data(). release_attributes_data() calls kset_unregister(wmi_priv.main_dir_kset); but before this commit it was missing a "wmi_priv.main_dir_kset = NULL;" statement; and after calling release_attributes_data() the sysman_init() error handling does this: if (wmi_priv.main_dir_kset) { kset_unregister(wmi_priv.main_dir_kset); wmi_priv.main_dir_kset = NULL; } Which causes a second kset_unregister(wmi_priv.main_dir_kset), leading to a double-free, which causes a crash. Add the missing "wmi_priv.main_dir_kset = NULL;" statement to release_attributes_data() to fix this double-free crash.

Disabling CQL (when enabled) before issuing the DYTC_CMD_RESET to get back to balanced mode and re-enabling it afterwards again, like the code already does when switching to low-power / performance mode fixes this.

2021-03-21platform/x86: thinkpad_acpi: Allow the FnLock LED to change stateEsteve Varela Colominas1-1/+7
On many recent ThinkPad laptops, there's a new LED next to the ESC key, that indicates the FnLock status. When the Fn+ESC combo is pressed, FnLock is toggled, which causes the Media Key functionality to change, making it so that the media keys either perform their media key function, or function as an F-key by default. The Fn key can be used the access the alternate function at any time. With the current linux kernel, the LED doens't change state if you press the Fn+ESC key combo. However, the media key functionality *does* change. This is annoying, since the LED will stay on if it was on during bootup, and it makes it hard to keep track what the current state of the FnLock is. This patch calls an ACPI function, that gets the current media key state, when the Fn+ESC key combo is pressed. Through testing it was discovered that this function causes the LED to update correctly to reflect the current state when this function is called. The relevant ACPI calls are the following: \_SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled. \_SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

2021-03-08platform/x86: wmi: Make remove callback return voidUwe Kleine-König9-19/+10
The driver core ignores the return value of struct bus_type::remove() (and so wmi_dev_remove()) because there is only little that can be done. To simplify the quest to make this function return void, let struct wmi_driver::remove() return void, too. All implementers of this callback return 0 already and this way it should be obvious to driver authors that returning an error code is a bad idea.

2021-03-08platform: x86: ACPI: Get rid of ACPICA message printingRafael J. Wysocki3-6/+3
A few x86 platform drivers use ACPI_DEBUG_PRINT() or ACPI_EXCEPTION() for printing messages, but that is questionable, because those macros belong to ACPICA and they should not be used elsewhere. In addition, ACPI_DEBUG_PRINT() requires special enabling to allow it to actually print the message, which is a nuisance, and the _COMPONENT symbol generally needed for that is not defined in any of the files in question. For this reason, replace the ACPI_DEBUG_PRINT() in lg-laptop.c with pr_debug() and the one in xo15-ebook.c with acpi_handle_debug() (with the additional benefit that the source object can be identified more easily after this change). Also drop the ACPI_MODULE_NAME() definitions that are only used by the ACPICA message printing macros from those files and from wmi.c and surfacepro3_button.c (while at it). Signed-off-by: Rafael J.

2021-03-08platform/x86: thinkpad_acpi: Handle keyboard cover attach/detach eventsAlexander Kobel1-0/+23
Those events occur when a keyboard cover is attached to a ThinkPad X1 Tablet series device. Typically, they are used to switch from normal to tablet mode in userspace; e.g., to offer touch keyboard choices when focus goes to a text box and no keyboard is attached, or to enable autorotation of the display according to the builtin orientation sensor. intel-vtbn already recognizes those events. To avoid sending duplicate events to userspace, they are simply ignored. Thus, this patch only avoids warnings about unknown and unhandled HKEYs 0x4012 and 0x4013. For more information about the background and potential improvements for different types of attachment options, such as the Pico cartridge dock module, see https://lore.kernel.org/platform-driver-x86/38cb8265-1e30-d547-9e12-b4ae290be737@a-kobel.de/ Signed-off-by: Alexander Kobel <a-kobel@a-kobel.de> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Link: https://lore.kernel.org/r/83a0e45f-590d-0c7d-0afd-00a5a6322bd0@a-kobel.de Signed-off-by: Hans de Goede <hdegoede@redhat.com>
