In nuc900_dma_hw_params(), if snd_pcm_lib_malloc_pages failed it returns without calling spin_unlock_irqrestore(). Since snd_pcm_lib_malloc_pages() does not touch struct nuc900_audio, we don't need to hold the lock while calling snd_pcm_lib_malloc_pages(). Fix it by moving spin_lock_irqsave() down to after snd_pcm_lib_malloc_pages(). In nuc900_dma_prepare(), spin_unlock_irqrestore() is missing in the error path. Fix it by removing the return in default case.
