The driver may sleep under a spin lock, and the function call path is: snd_cx18_pcm_hw_free (acquire the lock by spin_lock_irqsave) vfree --> may sleep To fix it, the "substream->runtime->dma_area" is passed to a temporary value, and mark it NULL when holding the lock. The memory is freed by vfree through the temporary value outside the lock holding.
