From 7d352a816056068daa8bd8c2be9f66a6afde8365 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 9 Jan 2023 19:39:47 -0600 Subject: [PATCH] habanalabs: Replace zero-length arrays with flexible-array members Zero-length arrays are deprecated[1] and we are moving towards adopting C99 flexible-array members instead. So, replace zero-length arrays in a couple of structures with flex-array members. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy() and help us make progress towards globally enabling -fstrict-flex-arrays=3 [2].
