Subject: [PATCH v19 6/6] drm/i915/selftests: Rename functions names

pm_resume and pm_suspend might be conflict with the ones defined in
include/linux/suspend.h. Rename pm_resume{suspend} to
i915_pm_resume{suspend} since they are only used here.

I agree with the rationale here.

Do you need this to be part of your series, or shall we just pick this
up for i915? (We might consider renaming to something else or prefix the
functions with _ though, as we also have existing i915_pm_suspend and
i915_pm_resume elsewhere.)

BR,
Jani.

This patch can be separated from the series, thanks.
