From 8bf3d4c535c2b9689c2979b281c24e9f59c2f4ad Mon Sep 17 00:00:00 2001 From: Henrique de Moraes Holschuh Date: Sat, 30 May 2009 13:25:09 -0300 Subject: 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.
