From 955a9d202f470019f42979f0d1caec98843e39ce Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 11 Nov 2014 14:44:57 -0800 Subject: irda: Convert IRDA_DEBUG to pr_debug Use the normal kernel debugging mechanism which also enables dynamic_debug at the same time. Other miscellanea: o Remove sysctl for irda_debug o Remove function tracing like uses (use ftrace instead) o Coalesce formats o Realign arguments o Remove unnecessary OOM messages Signed-off-by: Joe Perches Signed-off-by: David S.
