Subject: [PATCH 4.19 29/32] ACPI: video: Shortening quirk list by identifying Clevo by board_name only

From: Werner Sembach <wse@...edocomputers.com>

commit f0341e67b3782603737f7788e71bd3530012a4f4 upstream.

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.
