Subject: efi: initialize efi.runtime_version to make
query_variable_info/update_capsule workable
From: Seiji Aguchi <[email protected]>
commit d6cf86d8f23253225fe2a763d627ecf7dfee9dae upstream.
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.
