Subject: [PATCH 2/4] sound: codecs: pcm1792a: add define for register
Date: Fri, 20 Nov 2015 11:09:15 +0100	[thread overview]
Message-ID: <1448014157-36526-3-git-send-email-raphael.poggi@avalun.com> (raw)
In-Reply-To: <1448014157-36526-1-git-send-email-raphael.poggi@avalun.com>

From: Raphael Poggi <poggi.raph@gmail.com>

Use define for register instead of number, when it is possible.
Doing this, make easier to read and use in the code.
