From 12351a91da97b414eec8cdb09f1d9f41e535a401 Mon Sep 17 00:00:00 2001 From: Li Qiang Date: Wed, 14 Dec 2016 18:30:21 -0800 Subject: [PATCH] audio: ac97: add exit function MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit http://git.qemu.org/?p=qemu.git;a=patch;h=12351a91da97b414eec8cdb09f1d9f41e535a401 this patch is from qemu-git Currently the ac97 device emulation doesn't have a exit function, hot unplug this device will leak some memory. Add a exit function to avoid this.
