+Subject: [PATCH] Cherry-pick 279334@main (36d1b5d7c0ef). <bug>
+
+    Remove ARM-specific declarations in FELighting.h unneeded after 272873@main
+
+    Unreviewed build fix.
+
+    * Source/WebCore/platform/graphics/filters/FELighting.h: Remove unneeded
+      declarations for the getPowerCoefficients() and platformApplyNeon()
+      functions, which are now defined elsewhere; and were causing a build
+      failure due to usage of the protected LightingData type.
+    * Source/WebCore/platform/graphics/cpu/arm/filters/FELightingNeonParallelApplier.cpp:
+      (WebCore::FELightingNeonParallelApplier::applyPlatformParallel const):
+      Add missing LightType:: namespace to uses of LS_POINT and LS_SPOT.
