From 10973152f2f8f9d266e91c78abf1dca3514da775 Mon Sep 17 00:00:00 2001 From: David Yang Date: Fri, 4 Sep 2026 21:47:46 +0800 Subject: [PATCH] net: dsa: motorcomm: Handle degenerated blink delays The LED core defines delay_on == 0 as steady off and delay_off == 0 as steady on, which was treated as a blink in our LED driver. Fix it.
