+Subject: [PATCH] driver: char: rpivid: Destroy the legacy device on
+ remove
+
+The legacy name support created a new device that was never destroyed.
+If the driver was unloaded and reloaded, it failed due to the
+device already existing.
+
+Fixes: "75f1d14 driver: char: rpivid - also support legacy name"
