Subject: Check the returned audio_buf_info fields
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=29ddf27b72960d6e6b115cd69812c9c57b2a7b13;p=qemu.git

Check the returned audio_buf_info fields

At least on one system zero is returned in either fragsize or
fragstotal (reported by Dave Scott), this results in an audio_calloc
failing the audio_bug check and another ominous error message. Fail
early and blame the system.
