From c90ff6e67cd979cd25e5264c680f1a5392473ce4 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Mon, 17 Nov 2014 10:48:21 +0000 Subject: [PATCH] ASoC: wm_adsp: Avoid attempt to free buffers that might still be in use commit 9da7a5a9fdeeb76b2243f6b473363a7e6147ab6f upstream. We should not free any buffers associated with writing out coefficients to the DSP until all the async writes have completed. This patch updates the out of memory path when allocating a new buffer to include a call to regmap_async_complete.
