thinkpad-acpi: silence bogus warning when ACPI video is disabled
Make use of acpi_video_backlight_support() also in hotkey_init, to make sure this doesn't happen: thinkpad_acpi: This ThinkPad has standard ACPI backlight brightness control, supported by the ACPI video driver thinkpad_acpi: Disabling thinkpad-acpi brightness events by default... thinkpad_acpi: Standard ACPI backlight interface not available, thinkpad_acpi native brightness control enabled thinkpad_acpi: detected a 16-level brightness capable ThinkPad Note that this is purely cosmetic, there is absolutely _no_ change in behaviour. Those events are sometimes enabled at runtime by userspace, but the driver never enables them by itself unless someone messed with the default keymaps.
