Subject: [PATCH AUTOSEL 6.4 10/13] ACPI: video: Add backlight=native DMI quirk for Apple iMac12,1 and iMac12,2
Date: Fri, 8 Sep 2023 14:00:56 -0400 [thread overview]
Message-ID: <20230908180100.3458151-10-sashal@kernel.org> (raw)
In-Reply-To: <20230908180100.3458151-1-sashal@kernel.org>
From: Hans de Goede <hdegoede@redhat.com>
[ Upstream commit 8cf04bb321f036dd2e523e993897e0789bd5265c ]
Linux defaults to picking the non-working ACPI video backlight interface
on the Apple iMac12,1 and iMac12,2.
Add a DMI quirk to pick the working native radeon_bl0 interface instead.
