From f938f3485c385b9b5c796b2e93427c015a7d18fa Mon Sep 17 00:00:00 2001 From: Stuart Henderson Date: Tue, 19 Feb 2019 17:31:57 +0000 Subject: ASoC: wm_adsp: Update cached error state on trigger If a compressed stream is restarted after getting an error, the cached error value will still be used on the next pointer request, preventing the stream from starting. Resolve this by ensuring the error status is updated on trigger start.
