From 981b22b8777df7de070be1803f6d7ed4f634a43c Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 2 Mar 2021 07:21:38 +0100 Subject: tty: remove TTY_LDISC_MAGIC First, it is never checked. Second, use of it as a debugging aid is at least questionable. With the current tools, I don't think anyone used this kind of thing for debugging purposes for years. On the top of that, e.g. serdev does not set this field of tty_ldisc_ops at all. So get rid of this legacy.
