From 8ef111db5e077c09529b9446e41d893663d04d60 Mon Sep 17 00:00:00 2001 From: Pierre-Louis Bossart Date: Mon, 7 Jun 2021 17:22:34 -0500 Subject: [PATCH] ASoC: rt715-sdw: use first_hw_init flag on resume [ Upstream commit dbc07517ab173688ef11234d1099bc1e24e4f14b ] The intent of the status check on resume was to verify if a SoundWire peripheral reported ATTACHED before waiting for the initialization to complete. This is required to avoid timeouts that will happen with 'ghost' devices that are exposed in the platform firmware but are not populated in hardware. Unfortunately we used 'hw_init' instead of 'first_hw_init'. Due to another error, the resume operation never timed out, but the volume settings were not properly restored.
