Subject: [PATCH 02/16] tty: remove flags from struct tty_ldisc_ops
Date: Tue, 14 Sep 2021 11:11:20 +0200 [thread overview]
Message-ID: <20210914091134.17426-2-jslaby@suse.cz> (raw)
In-Reply-To: <20210914091134.17426-1-jslaby@suse.cz>
The last user was apparently removed by commit a352def21a64 (tty: Ldisc
revamp) in 2008. So remove the field completely, the only setter
(n_tty_inherit_ops) and also its only possible value
(LDISC_FLAG_DEFINED).
