From: Armin Wolf W_Armin@gmx.de
commit e527a6127223b644e0a27b44f4b16e16eb6c7f0a upstream.
The global hci_hotkey_quickstart quirk flag is tested in toshiba_acpi_enable_hotkeys() before the quirk flag is properly initialized based on SMBIOS data. This causes the quirk to be applied to all models, some of which behave erratically as a result.
Fix this by initializing the global quirk flags during module initialization before registering the ACPI driver. This also allows us to mark toshiba_dmi_quirks[] as __initconst.
