[PATCH][next] ACPICA: iASL: Replace zero-length array with flexible-array member

From: Gustavo A. R. Silva
Date: Wed Feb 16 2022 - 15:25:09 EST


There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].
