the dc_init_descriptor_list actually returns a +ve error return codes, which is abnormal as other functions in kernel return -ve error codes on failure. so replace the return codes of this function with -ve values to make the consistency with the other functions in kernel. Also make the dc_init_descriptor_list static as its never called anywhere except in this file and move the function prototype from the headerfile into the c file as its referred only in this c file.
