Luckly i've patched kernel tree for 4.4-rc2 :-)

The only change i've made to original patch was in intel_hdmi.c - some variables were gone so i tried to adapt patch to this situation (with my not-high coding level ). Here is patch for intel_hdmi.c from 4.4-rc2 kernel. With this patch everything worked 100% as before:
