From 5da7f924a41949797875c98a776dca1737a0f372 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 28 Jan 2015 17:32:22 +0100 Subject: [PATCH] ALSA: usx2y: Move UAPI definition into include/uapi/sound/usb_stream.h The user-space API definition for usb_stream stuff should be moved to include/uapi/sound to be exposed publicly. While we're at it, add the missing ifdef guard for double inclusion, too.
