Terratec Cinergy T2 driver leaves lsmod used cnt at -1, after sleep or
usb reconnect.
Driver can’t be removed with rmmod and modprobe -r crashes kernel.
After reconnect or wake up after sleep, cinergyt2 seems to be properly
initialized, but can’t be used by kaffeine. The system must be restarted
to be able to use the CinergyT2 again.
The only way to avoid this is to manually stop the driver with rmmod
before disconnect or sleep.
Tested on Thinkpad X131e Ubuntu Mate 21.04 5.11.0-34-generic x86_64
and several other.
The only reference to the problem that I have found is this:
https://linuxtv.org/pipermail/linux-dvb/2007-November/021577.html
Anyone have any ideas how to solve the problem or how to proceed?

The problem is that the module used count is incremented 1 time but
decremented 2 times by dvb_frontend. I guess there is a reason for the
call to dvb_prontend_put() twice, but to change that as suggested by
ref: https://linuxtv.org/pipermail/linux-dvb/2007-November/021577.html
affects other modules.
The best solution is to insert a call to try_module_get(THIS_MODULE) in
cinergyt2_frontend_attach() to prevent the module to be unloaded. This
change makes CinergyT2 to behave as expected after sleep and if
disconnected and connected again.
