From 49b8220cee4aa3d7aaaf42fd7f316b7f8fb710da Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Thu, 10 Aug 2023 11:15:05 +0200 Subject: tty: ldops: unify to u8 Some hooks in struct tty_ldisc_ops still reference buffers by 'unsigned char'. Unify to 'u8' as the rest of the tty layer does. Signed-off-by: "Jiri Slaby (SUSE)" Cc: Marcel Holtmann Cc: Johan Hedberg Cc: Luiz Augusto von Dentz Cc: Dmitry Torokhov Cc: "David S.
