            Bug ID: 199548
           Summary: i915_kms: missing iicbus_set_nonstop symbol after
                    277478 revision

>From revision 277487 commit (rewrite of the i915 gem io to more closely
follow Linux model) onward:

sys/dev/drm2/i915/intel_iic.c, function intel_iicbb_attach()

There is iicbus_set_nonstop(idev, true) called on function's end.

Such symbol doesn't exist in kernel nor is mentioned elsewhere in source codes

It prevent i915kms.ko to load because of unresolved symbol

The 277487 has been MFCed to STABLE/10 tree, so it is affected now as well.

I'm unsure about the purpose of such call as even Google know no other source
code mentioning function of such name.
