 A channelscan with the following command:

 {{{
 mythtv-setup -v general,channel --loglevel=debug

 }}}
 gives for each transport tuned the following message:

 {{{
 2019-01-28 20:22:19.187093 D  Draining DVB Event failed.
                         eno: Resource temporarily unavailable (11)

 }}}
 The message is given by the function drain_dvb_events in file
 dvbchannel.cpp.
 The events are read and discarded until there are no more events but then
 there is always an error message given. The error code is 11 or EAGAIN and
 this indicates that there is nothing more to read. In this case this means
 that there are no more events, which is the purpose of the function.\\
 The error message should only be given if the error code is other than
 EAGAIN.\\

 This is implemented in the attached patch.\\

 Tested with the local DVB-T and DVB-C signals.
