From 436e056c4ba368f13a5709a5a4a7f26fc238a5a6 Mon Sep 17 00:00:00 2001 From: Mans Rullgard Date: Wed, 3 Feb 2016 13:18:20 +0000 Subject: ASoC: mxs-saif: check BUSY bit in hw_params() only if not mclk_in_use If something else, typically a codec, has enabled mclk, the BUSY bit may be set when hw_params() is called without this being an error. This check thus causes intermittent failures to configure the sound device when used in such a manner. Fix this by making the test conditional on !saif->mclk_in_use.
