From 94a93e5f85040114d6a77c085457b3943b6da889 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 23 Jan 2013 17:06:02 -0300 Subject: [PATCH] [media] dvb_frontend: print a msg if a property doesn't exist If userspace calls a property that doesn't exist, it currently just returns -EINVAL. However, this is more likely a problem at the userspace application, calling it with a non-existing property. So, add a debug message to help tracking it.
