From 347d1c4b0779cbeabaebb9b8e9967afe28db22f1 Mon Sep 17 00:00:00 2001 From: Slawomir Blauciak Date: Mon, 3 Jun 2019 11:20:32 -0500 Subject: [PATCH] ASoC: SOF: ipc: replace fw ready bitfield with explicit bit ordering Previously the structure used bitfields, which do not guarantee bit ordering. This change makes sure the order is clearly defined. It also renames and repurposes the field for general use.
