commit ee2bd216e1fa9fa980e6ac702e5973d157c40c48

    ASoC: lpass-platform: fix uninitialized variable
    
    In commit 022d00ee0b55 ("ASoC: lpass-platform: Fix broken pcm data
    usage") the stream specific information initialization was broken, with
    the dma channel information not being initialized if there was no
    alloc_dma_channel() helper function.
    
    Before that, the DMA channel number was implicitly initialized to zero
    because the backing store was allocated with devm_kzalloc().  When the
    init code was rewritten, that implicit initialization was lost, and gcc
    rightfully complains about an uninitialized variable being used.
