Hi,

Linux kernel 5.1.5
According to https://github.com/torvalds/linux/blob/master/drivers/media/dvb-core/dvb_frontend.c#L908
this is to be expected, but for what reason?
The system is running VDR 2.2.0 with a Digital Devices Max S8.
Shouldn't this dprintk() be converted to dev_dbg(), since it doesn't buy
much for usual operation, does it?
While at it, do you have any idea, how to avoid these:
2019-05-28T18:56:11.099140+02:00 kernel: [ 6298.161481] dmxdev: DVB (dvb_dmxdev_filter_start): could not set feed
2019-05-28T18:56:11.099154+02:00 kernel: [ 6298.161487] dvb_demux: dvb_demux_feed_del: feed not in list (type=1 state=0 pid=ffff)
It's significantly less frequent compared to the former call, but
also quite nagging.
Thanks for consideration.
Cheers,
Pete
