From 38eb85d9da568004a5d3b31547cdd3e7c22d21b3 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 2 Jun 2014 17:41:10 +0200 Subject: [PATCH] acpi-video: Add use native backlight quirk for the ThinkPad W530 Like all of the other *30 ThinkPad models, the W530 has a broken acpi-video backlight control. Note in order for this to actually fix things on the ThinkPad W530 the commit titled: "nouveau: Don't check acpi_video_backlight_support() before registering backlight" is also needed. https://bugzilla.redhat.com/show_bug.cgi?id=1093171 Bugzilla: 1093171 Upstream-status: Queued for 3.16 Cc: stable@vger.kernel.org Signed-off-by: Hans de Goede --- drivers/acpi/video.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/drivers/acpi/video.c b/drivers/acpi/video.c index df1626d2ba10..caa4d8fc3458 100644 --- a/drivers/acpi/video.c +++ b/drivers/acpi/video.c @@ -469,6 +469,14 @@ static struct dmi_system_id video_dmi_table[] __initdata = { }, { .callback = video_set_use_native_backlight, + .ident = "ThinkPad W530", + .matches = { + DMI_MATCH(DMI_SYS_VENDOR, "LENOVO"), + DMI_MATCH(DMI_PRODUCT_VERSION, "ThinkPad W530"), + }, + }, + { + .callback = video_set_use_native_backlight, .ident = "ThinkPad X230", .matches = { DMI_MATCH(DMI_SYS_VENDOR, "LENOVO"), -- 1.9.3
