[alsa-devel] [PATCH] [v2] ASoC: atmel-classd: improve Kconfig dependencies
Commit 061981ff8cc8 ("ASoC: atmel: properly select dma driver state") changed the way that the dependencies are handled, but then the Class D amplifier support got merged, which used the old method.
This seems to have triggered a very rare randconfig condition for me now, leading to a link error:
sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_set_audio': atmel_ssc_dai.c:(.text+0x79c): undefined reference to `atmel_pcm_dma_platform_register' atmel_ssc_dai.c:(.text+0x79c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `atmel_pcm_dma_platform_register' sound/soc/atmel/atmel_ssc_dai.o: In function `atmel_ssc_put_audio': atmel_ssc_dai.c:(.text+0xf24): undefined reference to `atmel_pcm_dma_platform_unregister' atmel_ssc_dai.c:(.text+0xf24): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `atmel_pcm_dma_platform_unregister'
This changes the SND_ATMEL_SOC_DMA option so it gets built whenever one of the two users (SND_ATMEL_SOC_SSC_DMA and SND_ATMEL_SOC_CLASSD) is enabled, with the twist that we make it built-in when SND_ATMEL_SOC_SSC is built-in, even if one of the other two is a module.
I think this captures best what the real dependency in the hardware is, and it simplifies the logic a bit.
Fixes: e0a25b6d1862 ("ASoC: atmel-classd: add the Audio Class D Amplifier") Signed-off-by: Arnd Bergmann arnd@arndb.de --- v2: rewrite the change completely, after running into a new regression.
I'm putting it out on the list so we can review the change together, but I'm still doing more testing at the same time. If I don't reply by Dec 6, nothing new has come up. --- sound/soc/atmel/Kconfig | 5 ++--- 1 file changed, 2 insertions(+), 3 deletions(-)

I really think the only required dependency for SND_ATMEL_SOC_CLASSD is SND_SOC_GENERIC_DMAENGINE_PCM. It comes with SND_ATMEL_SOC_DMA but it doesn't actually use anything provided specifically by atmel-pcm-dma.c
Basically, it handles all of its DMA operations itself.
