[alsa-devel] [PATCH 06/24] ALSA: usb: Remove superfluous snd_dma_continuous_data()

[Takashi Iwai]

The recent change (commit b8a7d422280c: "ALSA: memalloc: Allow NULL
device for SNDRV_DMA_TYPE_CONTINOUS type") made the PCM preallocation
helper accepting NULL as the device pointer for the default usage.
Drop the snd_dma_continuous_data() usage that became superfluous from
the callers.
