+Subject: [PATCH] vt6656: Use request_firmware() to load firmware
+
+commit 31d5bbf3da8c3c9de5944f2c09cbc7ea5a72bdb4 upstream.
+
+The file added to linux-firmware is a copy of the current array which
+does not have a recognisable header, so no validation is done.
+
+Change the firmware version check to accept newer versions.
