| Subject: ASoC: wm_adsp: Avoid attempt to free buffers that might still be in use |
| |
| From: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> |
| |
| 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. |
