Subject: [PATCH v4 09/13] ALSA: hda/ca0132: add the ability to set src_id on scp commands
Date:   Mon,  7 May 2018 22:31:17 -0400
Message-Id: <1525746683-18535-10-git-send-email-conmanx360@gmail.com>
In-Reply-To: <1525746683-18535-1-git-send-email-conmanx360@gmail.com>
References: <1525746683-18535-1-git-send-email-conmanx360@gmail.com>
To:     unlisted-recipients:; (no To-header on input)
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch adds the ability to change the src_id on scp commands, which
is used in the dsp setup of the Recon3Di and the Sound Blaster Z. It
also makes sure to maintain backwards compatibility with the older
dspio_set_uint_param function, and sets it's src to the default 0x20.
