Commit 66601a29bb23 ("leds: class: If no default trigger is given, make hw_control trigger the default trigger") causes ledtrig-netdev to get set as default trigger on various network LEDs.

This causes users to hit a pre-existing AB-BA deadlock issue in ledtrig-netdev between the LED-trigger locks and the rtnl mutex, resulting in hung tasks in kernels >= 6.9.

Applied, thanks!
