# Function: check_add_drv()
#
# This function will check if the module has an entry in etc/name_to_major
# If not simply calls add_drv with the arguments given. If there is
# such an entry in name_to_major file, it adds entries in driver_aliases
# driver_classes and minor_perm if necessary.
# The syntax of this function is the same as add_drv.
