Subject: [PATCH 27/45] fbdev/core: simplify cursor_state setting in fbcon_ops::cursor()
Date: Thu, 18 Jan 2024 08:57:38 +0100

There is a switch decicing if cursor should be drawn or not. The whole
switch can be simplified to one line. Do this cleanup as a preparatory
work for the next patch. There, all the CM_* constants are removed.
