[Qemu-devel] [PATCH] configure: Fix build with ALSA audio driver

[Stefan Weil <sw@weilnetz.de>]

Since commit 417c9d72d48275d19c60861896efd4962d21aca2,
all configure tests normally run with -Werror.

Some of these tests now fail because they raised a compiler warning.

Here a build breakage for ALSA (configure --audio-drv-list=alsa) is fixed.

Signed-off-by: Stefan Weil <sw@weilnetz.de>

One of the buildbot jobs should be configured with all sound options:

--audio-card-list=ac97,es1370,sb16,cs4231a,adlib,gus,hda
--audio-drv-list=alsa,sdl,oss,esd,pa
--enable-mixemu

That would have detected this bug (and more potential bugs in the future).

Regards

Stefan W.
