From 7cdc887a00d79a1553009eb7afd308882e4b74d5 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Thu, 5 Jan 2017 21:48:08 +0900 Subject: ALSA: fireworks: enclose identifiers referred by single function Some identifiers are referred just by one functions. In this case, they can be put into the function definition. This brings two merits; readers can easily follow codes related to the identifiers, developers are free from name conflict. This commit moves such identifiers to each function definition.
