Subject: [linux-dvb] Driver use reference count becomes -2

Hi all,
I found that when I load the driver for vp7045 and unplug device from USB port, the driver's use reference count reaches a big weird number (Ex: 4294967294, in hex it is FFFFFFFE, means-2 I guess). This can be seen by command "lsmod|grep vp7045".
The Linux kernel version is 2.6.28. The source code is fetched from hg server of LinuxTV lately.
Does anyone know this bug? I guess somewhere mishandled the use count by accidentally decremented.
Thank you!
Bob
