The two uses of hw_error() come from commit 0d9acba: * When qemu_new_timer() fails. It couldn't fail back then, and it can't fail now. Drop the unreachable error handling. * When no_audio_driver can't be initialized. It couldn't fail back then, and it can't fail now. Replace the error handling by an assertion.
