From 1c75adb22d49ca9389333ca5e6939052a7203111 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Thu, 13 Jun 2024 22:59:09 +0200 Subject: ASoC: SOF: mediatek: Constify struct mtk_adsp_ipc_ops 'struct mtk_adsp_ipc_ops' is not modified in these drivers. Constifying this structure moves some data to a read-only section, so increase overall security. In order to do it, "struct mtk_adsp_ipc" also needs to be adjusted to this new const qualifier.
