Description hanchunchao inspur_group 2023-05-29 13:42:30 UTC 
Description of problem:

Since dvb_frontend_detach() is not called in ttusb_dec_exit_dvb(),
which is called when the device is disconnected, dvb_frontend_free()
is not finally called.

This causes a memory leak just by repeatedly plugging and
unplugging the device.
