I did not set this quirk for the transformer devices, since the quirk has to do with the handling of Fn + F7 (display off hotkey) by the embedded-controller. Since on transformer devices the keyboard is an USB device and not handled by the embedded-controller they do not need the wmi_backlight_set_devstate quirk, so I left it out. Chances are that your UX360 does need it. The purpose of the quirk is to make the embbedded controller send a KEY_DISPLAY_OFF event on FN + F7 and have it not do anything else (like turning off the backlight by itself). TL;DR: you should probably add: .wmi_backlight_set_devstate = true, to your new quirk_asus_use_lid_flip_devid quirk. > +}; > + > static int dmi_matched(const struct dmi_system_id *dmi) > { > pr_info("Identified laptop model '%s'\n", dmi->ident); > @@ -520,6 +524,16 @@ static const struct dmi_system_id asus_quirks[] = { > }, > .driver_data = &quirk_asus_use_kbd_dock_devid, > }, > + { > + .callback = dmi_matched, > + .ident = "ASUS ZenBook Flip UX360", > + .matches = { > + DMI_MATCH(DMI_SYS_VENDOR, "ASUSTeK COMPUTER INC."), > + /* Match UX360* */ > + DMI_MATCH(DMI_PRODUCT_NAME, "UX360"), > + }, > + .driver_data = &quirk_asus_use_lid_flip_devid, > + }, > {}, > }; > > diff --git a/drivers/platform/x86/asus-wmi.c b/drivers/platform/x86/asus-wmi.c > index ae6289d37faf..a628a7d9e066 100644 > --- a/drivers/platform/x86/asus-wmi.c > +++ b/drivers/platform/x86/asus-wmi.c > @@ -63,6 +63,7 @@ MODULE_LICENSE("GPL"); > #define NOTIFY_KBD_BRTTOGGLE 0xc7 > #define NOTIFY_KBD_FBM 0x99 > #define NOTIFY_KBD_TTP 0xae > +#define NOTIFY_LID_FLIP 0xfa > > #define ASUS_WMI_FNLOCK_BIOS_DISABLED BIT(0) > > @@ -375,6 +376,18 @@ static int asus_wmi_input_init(struct asus_wmi *asus) > } > } > > + if (asus->driver->quirks->use_lid_flip_devid) { > + result = asus_wmi_get_devstate_simple(asus, ASUS_WMI_DEVID_LID_FLIP); > + if (result >= 0) { > + input_set_capability(asus->inputdev, EV_SW, SW_TABLET_MODE); > + input_report_switch(asus->inputdev, SW_TABLET_MODE, result); > + } else if (result == -ENODEV) { > + pr_err("This device has lid_flip quirk but got ENODEV checking it.
