[PATCH] Chardev checking of overlapping ranges
The code in __register_chrdev_region checks that if the driver wishing to
register has the same major as an existing driver the new minor range is
strictly less than the existing minor range. However, it does not also
check that the new minor range is strictly greater than the existing minor
range. That is, if driver X has registered with major=x and minor=0-3,
__register_chrdev_region will allow driver Y to register with major=x and
minor=1-4.
