In the Linux kernel, the following vulnerability has been resolved: igc: fix a log entry using uninitialized netdev During successful probe, igc logs this: [ 5.133667] igc 0000:01:00.0 (unnamed netdevice) (uninitialized): PHC added ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The reason is that igcptpinit() is called very early, even before registernetdev() has been called. So the netdevinfo() call works on a partially uninitialized netdev. Fix this by calling igcptpinit() after registernetdev(), right after the media autosense check, just as in igb. Add a comment, just as in igb. Now the log message is fine: [ 5.200987] igc 0000:01:00.0 eth0: PHC added
