[PATCH 16/36] tty: use u8 for chars
From: Jiri Slaby (SUSE)
Date: Thu Aug 10 2023 - 06:12:58 EST
This makes all those 'unsigned char's an explicit 'u8'. This is part of
the continuing unification of chars and flags to be consistent u8.
This approaches tty_port_default_receive_buf(). Flags to be next.
