Subject: w1: have netlink search update kernel list
From: David Fries <David@xxxxxxxxx>
Reorganize so the netlink connector one wire search command will update
the kernel list of detected slave devices. Otherwise, a newly detected
device is unusable because unless it's in the kernel list of known devices
any commands will result in ENODEV status.
