A bugfix accidentally removed the implicit initialization of the dma channel number, causing undefined behavior when v->alloc_dma_channel is NULL:
sound/soc/qcom/lpass-platform.c: In function ‘lpass_platform_pcmops_open’: sound/soc/qcom/lpass-platform.c:83:29: error: ‘dma_ch’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This adds back an explicit initialization to zero, restoring the previous behavior for that case.
