+Subject: [PATCH 077/102] net-next: mediatek: use mdiobus_free() in favour of
+ kfree()
+
+The driver currently uses kfree() to clear the mii_bus. This is not the
+correct way to clear the memory and mdiobus_free() should be used instead.
+This patch fixes the two instances where this happens in the driver.
