According to ACPI spec 5, section 6.4.3.1 "24-Bit Memory Range Descriptor", minimum, maximum and address_length field in struct acpi_resource_memory24 is in granularity of 256-bytes. So shift 8-bit left to get correct address. Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com> --- drivers/acpi/resource.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
