[alsa-devel] Subject: [PATCH 1/1] set invalid dma channel to -1 (and properly check for it) since 0 is not an invalid channel but -1 is.

Set the invalid dma channel to -1 (and check properly for it) in pxa2xx_pcm_hw_free(). Was assuming 0 is an invalid channel number but 0 is a valid pxa dma channel num.
