Hi,
this patch fixes a memory leak which occurs when an em28xx card with DVB
extension is unplugged or its DVB extension driver is unloaded. In
dvb_fini(), dev->dvb must be freed before being set to NULL, as is done
in dvb_init() in case of error.
Note that this bug is also present in the latest stable kernel release.
Regards,
Francesco
