commit 8fa73ee44daefc884c53a25158c25a4107eb5a94 upstream.
Add a DMI quirk for Samsung Galaxy Book2 to fix an initial lid state detection issue.
The _LID device incorrectly returns the lid status as "closed" during boot, causing the system to enter a suspend loop right after booting.
The quirk ensures that the correct lid state is reported initially, preventing the system from immediately suspending after startup. It only addresses the initial lid state detection and ensures proper system behavior upon boot.
