From a4aa169aab5a621edaabb6b40d1b761bdb92b1f2 Mon Sep 17 00:00:00 2001 From: Elyes Haouas Date: Sun, 30 Jul 2023 12:59:50 +0200 Subject: include/acpi: Use C99 flexible arrays Use C99 flexible arrays instead of older style of one-element or zero-length arrays. It allows the compiler to generate errors when the flexible array does not occur at the end in the structure.
