From 046b44ab0f5a87ba5788606155c5a6761169616a Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Sun, 27 Aug 2023 09:41:42 +0200 Subject: tty: n_tty: remove unsigned char casts from character constants We compile with -funsigned-char, so all character constants are already unsigned chars. Therefore, remove superfluous casts.
