From 3886518fdb6d4c3f5a84648474a857d63749af78 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Fri, 12 May 2023 13:16:54 -0500 Subject: [PATCH] ASoC: SOF: Intel: hda-dai: simplify .prepare callback MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The code has been cleaned-up multiple times, but while adding the new abstractions for DMIC/SSP/SoundWire it appears that we don't really need a specific sequence for .prepare, and we can reuse what .hw_params already does.
