Q: Given the following code slice:
```
1 int pinctrl_enable(struct pinctrl_dev *pctldev)
3 	int error;
5 	error = pinctrl_claim_hogs(pctldev);
6 	if (error) {
7 		dev_err(pctldev->dev, "could not claim hogs: %i\n",```
which has a CWE-457 vulnerability at line:
```
7 		dev_err(pctldev->dev, "could not claim hogs: %i\n",
```
Please analyze the root cause of the vulnerability.
