[linux-dvb] Unable to remove driver modules

[Martin Neuditschko <yosuke.tomoe@gmx.net>]

I tried to unload the driver with "make rmmod" and this failed because
kvdr was running (kvdr is something like xawtv). This was clear
because kvdr blocks the devices. But after killing the application
I also can not remove the drivers:

melchior:/usr/local/src/newstruct_020702/driver # make rmmod

If I restart the computer the drivers surely are unloaded,
but I don't want to restart the PC every time I make such
a mistake. Has someone an idea how to solve this problem?

best regards
