A value of efi.runtime_version is checked before calling
update_capsule()/query_variable_info() as follows.
But it isn't initialized anywhere.
<snip>
static efi_status_t virt_efi_query_variable_info(u32 attr,
u64 *storage_space,
u64 *remaining_space,
u64 *max_variable_size) {
if (efi.runtime_version < EFI_2_00_SYSTEM_TABLE_REVISION)
return EFI_UNSUPPORTED;
<snip>
This patch initializes a value of efi.runtime_version at boot time.
Acked-by: Matthew Garrett <mjg@redhat.com>

Thanks, I picked this up just so it doesn't get lost. It will probably
go to Linus via Peter Anvin.

Should I take that as an Acked-by: on your part?
