Subject: [PATCH] usb: gadget: u_audio: Remove superfluous snd_dma_continuous_data()
Date: Fri,  8 Nov 2019 17:42:14 +0100
Message-ID: <20191108164214.611-1-tiwai@suse.de> (raw)

The recent change (commit 08422d2c559d: "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.

Signed-off-by: Takashi Iwai <tiwai@suse.de>

Note that the prerequisite commit 08422d2c559d is found currently only
on for-next branch of sound git tree, so please give ACK if it's OK,
so that I can apply on top of it.  Thanks!
