From 97c5209b3d374a25ebdb4c2ea9e9c1b121768da0 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 14 Jun 2023 10:03:59 +0300 Subject: [PATCH] leds: trigger: netdev: uninitialized variable in netdev_trig_activate() The qca8k_cled_hw_control_get() function which implements ->hw_control_get sets the appropriate bits but does not clear them. This leads to an uninitialized variable bug. Fix this by setting mode to zero at the start.
