ACPICA: Use designated initializers
The struct layout randomization plugin detects and randomizes any structs that contain only function pointers. Once layout is randomized, all initialization must be designated or the compiler will misalign the assignments. This switches all the ACPICA function pointer struct to use designated initializers, using the proposed upstream ACPICA macro: https://github.com/acpica/acpica/pull/248/ Signed-off-by: Kees Cook <keescook@chromium.org> Signed-off-by: Rafael J.
