Hi!
quoted
+struct ncp5623_led {
+	bool active;
+	unsigned int led_no;
+	struct led_classdev ldev;
+	struct work_struct work;
+	struct ncp5623_priv *priv;
+};
+
+struct ncp5623_priv {
+	struct ncp5623_led leds[NCP5623_MAX_LEDS];
Please allocate memory dynamically, depending on the number
of LEDs defined in a Device Tree.
MAX_LEDs is three. Are you sure overhead of dynamic allocation is
worth it?

And if this is for RGB leds... very probably device will want to use
all 3 channels.

Best regards,
