Subject: [PATCH 02/29] staging: bcm2835-audio: Remove redundant spdif stream ctls
Date: Tue,  4 Sep 2018 17:58:31 +0200
Message-ID: <20180904155858.8001-3-tiwai@suse.de> (raw)
In-Reply-To: <20180904155858.8001-1-tiwai@suse.de>

The "IEC958 Playback Stream" control does basically the very same
thing as "IEC958 Playback Default" redundantly.  The former should
have been stream-specific and restored after closing the stream, but
we don't do in that way.

Since it's nothing but confusion, remove this fake.
