[PATCH v3 4/8] drm/i915/reset: add intel_display_reset_test()

[Jani Nikula]

Add a helper for checking if we want to test display reset regardless of
whether it's strictly necessary. This will come in handy in follow-up
work where we want to check this from gt reset side.

v2: Drop superfluous newline
