[ Upstream commit fce9642c765a18abd1db0339a7d832c29b68456a ]
node_to_amd_nb() is defined to NULL in non-AMD configs:
drivers/platform/x86/amd/hsmp/plat.c: In function 'init_platform_device': drivers/platform/x86/amd/hsmp/plat.c:165:68: error: dereferencing 'void *' pointer [-Werror] 165 | sock->root = node_to_amd_nb(i)->root; | ^~ drivers/platform/x86/amd/hsmp/plat.c:165:68: error: request for member 'root' in something not a structure or union
Users of the interface who also allow COMPILE_TEST will cause the above build error so provide an inline stub to fix that.
