From 6b194fedac7424b00d655aa2d175a08b84aa99fd Mon Sep 17 00:00:00 2001 From: Jonathan Denose Date: Wed, 12 Mar 2025 22:51:00 +0900 Subject: [PATCH] ACPI: video: force native for Apple MacbookPro11,2 and Air7,2 BugLink: https://bugs.launchpad.net/bugs/2102118 [ Upstream commit 295991836b23c12ddb447f7f583a17fd3616ad7d ] There is a bug in the Macbook Pro 11,2 and Air 7,2 firmware similar to what is described in: commit 7dc918daaf29 ("ACPI: video: force native for Apple MacbookPro9,2") This bug causes their backlights not to come back after resume. Add DMI quirks to select the working native Intel firmware interface such that the backlght comes back on after resume.
