4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Takashi Iwai <tiwai@xxxxxxx> commit 97cc2ed27e5a168cf423f67c3bc7c6cc41d12f82 upstream. The hdac_acomp object in hdac_i915.c is left as assigned even after binding with i915 actually fails, and this leads to the WARN_ON() at the next load of the module.
