  To: alsa-devel; +Cc: tiwai, broonie, Keyon Jie, pierre-louis.bossart

The check (tplg->pass == le32_to_cpu(hdr->type)) makes no sense as it is
comparing two different enums, refine the element loading functions, and
log the information when the header is being parsed in the corresponding
parsing pass.
