In the Linux kernel, the following vulnerability has been resolved:

mm/slab: make __free(kfree) accept error pointers

Currently, if an automatically freed allocation is an error pointer that
will lead to a crash. An example of this is in wm831x_gpio_dbg_show().

171 char *label __free(kfree) = gpiochip_dup_line_label(chip, i);
172 if (IS_ERR(label)) {
173 dev_err(wm831x->dev, "Failed to duplicate label\n");
174 continue;
175 }

The auto clean up function should check for error pointers as well,
otherwise we're going to keep hitting issues like this.
