Subject: [PATCH] Disable final processing of .o files with binary blobs
Due to the fact that the driver is unmaintained, and can't be adapted
to the current Linux kernel security standards (e.g. IBT), as it has a
proprietary blob; as this is likely to be an ever-growing security risk:
Use at your own risk; no warranty of any kind is provided.
