| Subject: [PATCH] ASoC: atmel: fix atmel_ssc_set_audio link failure |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |

| |
| commit 9437bfda00f3b26eb5f475737ddaaf4dc07fee4f upstream. |
| |
| The ssc audio driver can call into both pdc and dma backends. With the |
| latest rework, the logic to do this in a safe way avoiding link errors |
| was removed, bringing back link errors that were fixed long ago in commit |
| 061981ff8cc8 ("ASoC: atmel: properly select dma driver state") such as |
| |
| sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio': |
| atmel_ssc_dai.c:(.text+0xac): undefined reference to `atmel_pcm_pdc_platform_register' |
| |
| Fix it this time using Makefile hacks and a comment to prevent this |
| from accidentally getting removed again rather than Kconfig hacks. |
| |
| Fixes: 18291410557f ("ASoC: atmel: enable SOC_SSC_PDC and SOC_SSC_DMA in Kconfig") |
