From 6e8661ed303f2f212436bfbee65f474077df55f6 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 28 May 2013 19:44:24 -0700 Subject: [PATCH] staging: fwserial: Use normal logging styles Logging messages without newline termination are subject to interleaving by other messages. Avoid this by adding newlines to each message. Neaten fwtty_ logging macros. Convert driver_err to pr_err. Add #define pr_fmt to prefix those messages. Remove now unused driver_err macro.
