From 8d7bda51888d14c07cbebacc5a10be776477bb63 Mon Sep 17 00:00:00 2001 From: Alexander Stein Date: Sun, 26 May 2013 20:06:50 +0200 Subject: w1: add family based automatic module loading This patch allows the 1-wire bus to autoload the corresponding module for each slave being attached. This works similar to bluetooth protocols.
