Subject: drm/i915/debugfs: Remove i915_energy_uJ
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6311d260a1794d8ccef0ac8b39405fea0e1d9474;p=openwrt%2Fstaging%2Fblogic.git

drm/i915/debugfs: Remove i915_energy_uJ

Last IGT user (intel_gpu_overlay) stopped using it in October 2019 so we
are good to remove the file.
