From 6e5710e71df19804f921f193744d615912b7a7cb Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Thu, 10 Aug 2023 11:14:37 +0200 Subject: tty: remove dummy tty_ldisc_ops::poll() implementations tty_ldisc_ops::poll() is optional and needs not be provided. It is equal to returning 0. So remove all those from the code. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Marcel Holtmann Cc: Johan Hedberg Cc: Luiz Augusto von Dentz Cc: "David S.
