From e2f24cb1b5daf9a4f6f3ba574c1fa74aab9807a4 Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Wed, 19 Apr 2023 23:07:40 +0200 Subject: [PATCH] leds: trigger: netdev: Drop NETDEV_LED_MODE_LINKUP from mode Putting NETDEV_LED_MODE_LINKUP in the same list of the netdev trigger modes is wrong as it's used to set the link state of the device and not to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the netdev trigger mode and should be external to it. Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool that will be true or false based on the carrier link. No functional change intended.
