5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Luke D. Jones luke@ljones.dev
[ Upstream commit 00aa846955fbfb04f7bc0c26c49febfe5395eca1 ]
Due to multiple types of tablet/lidflip, the existing code for handling these events is refactored to use an enum for each type.
