If kmalloc() fails in add_interval(), it could\nresult in a null pointer being inserted into the linked list,\nleading to illegal memory access when sub_interval() is called\nnext.\n\nThis patch adds an error handling for the add_interval(). If\nadd_interval() returns an error, the function will return early\nwith the error code."
