** Description changed:
When booting with secure boot and kernel lockdown is enabled, OpenCL is
unable to use my GPU (GeForce RTX 2080 SUPER). Running "clinfo" shows
- "Number of platforms 0". If I disable secure boot in my UFEI BIOS,
+ "Number of platforms 0". If I disable secure boot in my UEFI settings,
clinfo shows the details of my GPU as expected.
