From 9ec32cc703c17b9fd1695619695b84f6ed554fab Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 9 Sep 2015 03:40:39 -0300 Subject: [PATCH] [media] v4l2-compat-ioctl32: replace pr_warn by pr_debug Every time compat32 encounters an unknown ioctl it will call pr_warn. However, that's very irritating since it is perfectly normal that this happens. For example, applications often try to call an ioctl to see if it exists, and if that's used with an older kernel where compat32 doesn't support that ioctl yet, then it starts spamming the kernel log. So replace pr_warn by pr_debug.
