* Return the next match of ACPI device if another matching device was present
* at the moment of invocation, or NULL otherwise.
*
- * FIXME: The function does not tolerate the sudden disappearance of @adev, e.g.
- * in the case of a hotplug event. That said, the caller should ensure that
- * this will never happen.
- *
* The caller is responsible for invoking acpi_dev_put() on the returned device.
+ * On the other hand the function invokes acpi_dev_put() on the given @adev
+ * assuming that its reference counter had been increased beforehand.
*
* See additional information in acpi_dev_present() as well.
