From a287885f1e378bff5f58cee6d0fd16b886c4863b Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 30 Jan 2020 12:58:43 +0100 Subject: [PATCH] n_tty: check printk arguments for n_tty_trace When N_TTY_TRACE is undefined (the default), define n_tty_trace to use no_printk. That way, arguments are still checked during compilation.
