From f0341e67b3782603737f7788e71bd3530012a4f4 Mon Sep 17 00:00:00 2001 From: Werner Sembach wse@tuxedocomputers.com Date: Thu, 7 Jul 2022 20:09:53 +0200 Subject: [PATCH] ACPI: video: Shortening quirk list by identifying Clevo by board_name only
Taking a recent change in the i8042 quirklist to this one: Clevo board_names are somewhat unique, and if not: The generic Board_-/Sys_Vendor string "Notebook" doesn't help much anyway. So identifying the devices just by the board_name helps keeping the list significantly shorter and might even hit more devices requiring the fix.
