From: Paulo Zanoni <paulo.r.zan...@intel.com>
Any power domain will require the HW to be in PCI D0 state, so just do
the simple thing.
Dear maintainer: since intel_display_power_put() and
intel_display_power_get() are almost identical, git-am has failed to
apply the patch on my local machine once: it added both chunks to
put(), instead of one chunk to get() and another to put(). When you
apply this patch to your tree, please check if it is correct.
v2: - Add the warning above.
