> During module unloading, cdev_del be called to unmap cdev related
> kobject references and other cleanups(such as inode->i_cdev being set
> to NULL) which prevents the OOPS upon subsequent loading ,usage and
> unloading of modules(as seen in the mail thread:
> http://marc.theaimsgroup.com/?l=linux-kernel&m=114533640609018&w=2).
