ACPI / util: cast data to u64 before shifting to fix sign extension obj->buffer.pointer[i] should be cast to u64 to prevent an unintentional sign extension. For example, if pointer[7] is 0x80, then the value 0xffffffffff000000 is or'd into mask rather than the intended value 0xff00000000000000 Detected with static analysis by CoverityScan Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Rafael J.
