+Subject: [PATCH 683/773] overlays: Correct gpio-fan gpio flags for 4.19
+
+The gpio-fan overlay was submitted for the 4.14 kernel where the second
+value in the Device Tree gpios declaration was ignored (thanks to an
+old-style driver), allowing the fan-control output to be active-high
+even though the declaration appears to request it be active-low.
+The gpio-fan driver in 4.19 uses GPIO descriptors and honours the
+active-low flag that the overlay (accidentally?) supplies.
+
+Change/correct the flags field to mark the GPIO as active-high.
