Subject: [PATCH 09/15] ALSA: hda/ca0132 - Merge post-dsp functions + cleanup
Date:   Tue, 18 Sep 2018 14:33:37 -0400
Message-Id: <1537295625-8082-10-git-send-email-conmanx360@gmail.com>
In-Reply-To: <1537295625-8082-1-git-send-email-conmanx360@gmail.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This patch cleans up some of the formatting of the post-dsp load setup
functions, and also merges some of the sub functions into individual
ones.
