Hi Krzysztof,
kernel test robot noticed the following build errors:
[auto build test ERROR on broonie-sound/for-next]
[also build test ERROR on linus/master v6.12-rc2 next-20241011]
[If your patch is applied to the wrong git tree, kindly drop us a note.
And when submitting patch, we suggest to use '--base' as documented in

Commit 15c7fab0e047 ("ASoC: qcom: Move Soundwire runtime stream alloc to soundcards") moved the allocation of Soundwire stream runtime from the Qualcomm Soundwire driver to each individual machine sound card driver, except that it forgot to update SC7280 card. Just like for other Qualcomm sound cards using Soundwire, the card driver should allocate and release the runtime. Otherwise sound playback will result in a NULL pointer dereference or other effect of uninitialized memory accesses (which was confirmed on SDM845 having similar issue). Cc: stable@vger.kernel.org Cc: Alexey Klimov <alexey.klimov@linaro.org> Cc: Steev Klimaszewski <steev@kali.org> Fixes: 15c7fab0e047 ("ASoC: qcom: Move Soundwire runtime stream alloc to soundcards") Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- Not tested on hardware. The sc7280 sound card differs a bit from the ones I am working on, thus please kindly test and confirm. Without the patch KASAN should show something similar to: https://lore.kernel.org/linux-sound/20241009213922.999355-1-alexey.klimov@linaro.org/T/#u The patch should fix it. --- sound/soc/qcom/sc7280.c | 10 +++++++++- 1 file changed, 9 insertions(+), 1 deletion(-)
