The idea is to make it look something like this: #define QUIRK_TURN_ON_PANEL_ON_RESUME BIT(0) #define QUIRK_HCI_HOTKEY_QUICKSTART BIT(1) static const struct dmi_system_id toshiba_dmi_quirks[] = { { /* Toshiba Portégé R700 */ /* https://bugzilla.kernel.org/show_bug.cgi?id=21012 */ .matches = { DMI_MATCH(DMI_SYS_VENDOR, "TOSHIBA"), DMI_MATCH(DMI_PRODUCT_NAME, "PORTEGE R700"), }, .driver_data = (void *)QUIRK_TURN_ON_PANEL_ON_RESUME, }, { /* Toshiba Satellite/Portégé R830 */ /* Portégé: https://bugs.freedesktop.org/show_bug.cgi?id=82634 */ /* Satellite: https://bugzilla.kernel.org/show_bug.cgi?id=21012 */ .matches = { DMI_MATCH(DMI_SYS_VENDOR, "TOSHIBA"), DMI_MATCH(DMI_PRODUCT_NAME, "R830"), }, .driver_data = (void *)QUIRK_TURN_ON_PANEL_ON_RESUME, }, { /* Toshiba Satellite/Portégé Z830 */ .matches = { DMI_MATCH(DMI_SYS_VENDOR, "TOSHIBA"), DMI_MATCH(DMI_PRODUCT_NAME, "Z830"), }, .driver_data = (void *)QUIRK_TURN_ON_PANEL_ON_RESUME | QUIRK_HCI_HOTKEY_QUICKSTART, }, }; And then in toshiba_acpi_add() use: const struct dmi_system_id *dmi_id; long quirks = 0; dmi_id = dmi_first_match(toshiba_dmi_quirks); if (dmi_id) quirks = (long)dmi_id->driver_data; if (turn_on_panel_on_resume == -1) turn_on_panel_on_resume = !!(quirks & QUIRK_TURN_ON_PANEL_ON_RESUME); if (hci_hotkey_quickstart == -1) hci_hotkey_quickstart = !!(quirks & QUIRK_HCI_HOTKEY_QUICKSTART); This avoids duplicating the DMI match for the Z830 models and will also make it easier to add more DMI based quirks in the future.

The Z830 has some buttons that will only work properly as "quickstart" buttons. To enable them in that mode, a value between 1 and 7 must be used for HCI_HOTKEY_EVENT. Windows uses 0x5 on this laptop so use that for maximum predictability and compatibility. As there is not yet a known way of auto detection, this patch uses a DMI quirk table. A module parameter is exposed to allow setting this on other models for testing.
