From 069eb7b2b8fc47c7cb52e5a4af23ea98d939e3da Mon Sep 17 00:00:00 2001 From: Li Qiang Date: Wed, 14 Dec 2016 18:32:22 -0800 Subject: [PATCH] audio: es1370: 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=069eb7b2b8fc47c7cb52e5a4af23ea98d939e3da this patch is from qemu-git. Currently the es1370 device emulation doesn't have a exit function, hot unplug this device will leak some memory. Add a exit function to avoid this.
