From 2428a8fe2261e901e058d9ea8b6ed7e1b4268b79 Mon Sep 17 00:00:00 2001 From: Alex Dubov Date: Thu, 12 Apr 2007 16:59:18 +1000 Subject: [PATCH] tifm: move common device management tasks from tifm_7xx1 to tifm_core Some details of the device management (create, add, remove) are really belong to the tifm_core, as they are not hardware specific.
