Subject: [media] dvb_frontend: print a msg if a property doesn't exist
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=94a93e5f85040114d6a77c085457b3943b6da889;p=openwrt%2Fstaging%2Fblogic.git

[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.
