From 0f3dcf3b5d76669123bf99fec812b8b0acd60375 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Wed, 5 May 2021 11:19:04 +0200 Subject: tty: make fp of tty_ldisc_ops::receive_buf{,2} const Char pointer (cp) passed to tty_ldisc_ops::receive_buf{,2} is const. There is no reason for flag pointer (fp) not to be too. So switch it in the definition and all uses.
