From ca89f72092bdb42e077f2f64f417edad009ce0ef Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Mon, 8 May 2017 17:57:33 -0300 Subject: [PATCH] audio: Move arch_init audio code to hw/audio/soundhw.c MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There's no reason to keep the soundhw table in arch_init.c. Move that code to a new hw/audio/soundhw.c file. While moving the code, trivial coding style issues were fixed.
