Dear maintainer: since intel_display_power_put() and intel_display_power_get() are almost identical, git-am has failed 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. v3: - Rebase.
