In xhci_debugfs_create_slot(), kzalloc() can fail and dev->debugfs_private will be NULL. In xhci_debugfs_create_endpoint(), dev->debugfs_private is used without any null-pointer check, and can cause a null pointer dereference. To fix this bug, a null-pointer check is added in xhci_debugfs_create_endpoint(). This bug is found by a runtime fuzzing tool named FIZZER written by us.
