From ca775c629a366ded01aae69da8410f70aaf85de1 Mon Sep 17 00:00:00 2001 From: Evgeniy Polyakov Date: Fri, 20 May 2005 22:49:08 +0400 Subject: [PATCH] [PATCH] w1: new family structure. Removed some fields which are not required. First step for writing operations. Now only read and read name remain. Patch depends on w1 cleanups patch.
