Currently HD-audio driver on Intel Skylake or Broxteon gives an error message when binding with i915 audio component fails. However, this isn't any serious error on a system without Intel graphics. Indeed there are such systems, where a third-party codec (e.g. Creative) is put on the mobo while using other discrete GPU (e.g. Nvidia). Printing a kernel "error" message is overreaction in such a case.
This patch downgrades the print level for that message. For systems that mandate the i915 binding (e.g. Haswell or Broadwell HDMI/DP), another kernel error message is shown in addition to make clear what went wrong.
