From b18d1c2efa47f7fbf20a7ca4e121a991c3272326 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 16 Mar 2020 07:49:10 +0100 Subject: tty: n_hdlc, remove FILE and LINE from pr_debug As Joe suggests, dynamic debug can print module name and line number along with message. So remove __FILE__ and __LINE__ from all those pr_debug calls. Out of curiosity, I measured the savings, 200 bytes of code are gone.
