Message-Id: <200903260042.50236.david-b@pacbell.net>

Subject: [patch/rfc 2.6.29 2/2] MTD: support driver model updates
From: David Brownell <dbrownell@...rs.sourceforge.net>
Follow-on patch to the previous driver model patch for the MTD
framework. This one makes various MTD drivers connect to the
driver model tree, so /sys/devices/virtual/mtd/* nodes are no
longer present ... mostly drivers used on boards I have handy.
Based on a patch from Kay Sievers.
