+Subject: ACPI: video: Force backlight native for some TongFang devices
+
+From: Werner Sembach <wse@tuxedocomputers.com>
+
+commit c752089f7cf5b5800c6ace4cdd1a8351ee78a598 upstream.
+
+The TongFang PF5PU1G, PF4NU1F, PF5NU1G, and PF5LUXG/TUXEDO BA15 Gen10,
+Pulse 14/15 Gen1, and Pulse 15 Gen2 have the same problem as the Clevo
+NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2:
+They have a working native and video interface. However the default
+detection mechanism first registers the video interface before
+unregistering it again and switching to the native interface during boot.
+This results in a dangling SBIOS request for backlight change for some
+reason, causing the backlight to switch to ~2% once per boot on the first
+power cord connect or disconnect event. Setting the native interface
+explicitly circumvents this buggy behaviour by avoiding the unregistering
+process.

+Subject: ACPI: video: Shortening quirk list by identifying Clevo by board_name only
+
+From: Werner Sembach <wse@tuxedocomputers.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.
