From: Takashi Iwai Date: Mon, 4 Nov 2019 13:36:17 +0000 (+0100) Subject: usb: gadget: u_audio: Remove superfluous snd_dma_continuous_data() X-Git-Tag: v5.10.7~3493^2~95 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=67b2945d632328fa0245279e8281e34bf1c78ae2;p=platform%2Fkernel%2Flinux-rpi.git usb: gadget: u_audio: Remove superfluous snd_dma_continuous_data() The recent change (commit 08422d2c559d: "ALSA: memalloc: Allow NULL device for SNDRV_DMA_TYPE_CONTINUOUS 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.
