That's because you has dynamic debugs enabled!
modprobe dvb_core; echo -n 'module dvb_core +p' >
/sys/kernel/debug/dynamic_debug/control
modprobe dvb_usbv2; echo -n 'module dvb_usbv2 +p' >
/sys/kernel/debug/dynamic_debug/control
If you don't add dvb_core and dvb_usbv2 modules to
/sys/kernel/debug/dynamic_debug/control you will not see those.
I have added ratelimited version for those few debugs that are flooded
normally. This suppressed is coming from ratelimit - it does not print
all those similar debugs.
