[Qemu-devel] [PATCH v3 0/4] QOM'ify hw/audio files

[xiaoqiang zhao]

This patch set QOM'ify some files under hw/audio directory.
See each patch's commit message for details.

Changes in v3: 
* fix code style errors
* refine error_setg message format 

Changes in v2: 
Move AUD_open_in/out function into device realize stage
