Subject: [alsa-devel] [PATCH] ALSA: uapi: Drop unneeded typedefs
Date: Fri, 20 Dec 2019 17:15:55 +0100
Message-ID: <20191220161555.20232-1-tiwai@suse.de> (raw)

We kept some typedefs in uapi/sound/*.h so that the programs in
alsa-tools can be built.  Now that alsa-lib takes these and applies
the workarounds in its own, we don't need these typedefs any longer in
the kernel uapi side.  Let's drop them.
