From 975cc02a904ae385721f1bdb65eb1bcf707dfaf1 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 28 Jun 2013 11:56:49 +0200 Subject: ALSA: Replace the magic number 44 with const The char arrays with size 44 are for the name string of snd_ctl_elem_id. Define the constant and replace the raw numbers with it for clarifying better.
