| |
4.17-stable review patch. If anyone has any objections, please let me know.
------------------
From: Janakarajan Natarajan <Janakarajan.Natarajan@amd.com>
commit d30f370d3a4998c13ed3e5c8ef607d05be0a987a upstream.
Prevent a config where KVM_AMD=y and CRYPTO_DEV_CCP_DD=m thereby ensuring that AMD Secure Processor device driver will be built-in when KVM_AMD is also built-in.
v1->v2: * Removed usage of 'imply' Kconfig option. * Change patch commit message.
Fixes: 505c9e94d832 ("KVM: x86: prefer "depends on" to "select" for SEV")
