[Voyage-linux] Netdev led trigger crashes on ALIX running 3.12 kernel

[Punky Tse]

Hi Ted and Davor,

Thank you for confirming this.  This means the netdev trigger no longer 
works in 3.12 on or after.  When use with APU led driver, the problem 
already shows.  It is not APU led driver problem alone but is netdev 
trigger.

I would remove netdev trigger from the time being.

Regards,
Punky
