[PATCH] virt: sevguest: add CONFIG_CRYPTO dependency
Posted by Arnd Bergmann 2 years, 8 months ago

This driver fails to link when CRYPTO is disabled, or in a loadable module:

This has been present from when the driver was first added, so I think the 
correct Fixes: tag should be:

Fixes: fce96cf04430 ("virt: Add SEV-SNP guest driver")

Correct?

Thanks,
