[PATCH] auxdisplay: Remove unused functions

From: linux
Date: Sun Oct 06 2024 - 18:55:23 EST


From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>

cfag12864b_getrate() and cfag12864b_isenabled() were both added
in commit 70e840499aae ("[PATCH] drivers: add LCD support")
but never used.

Remove them.
