From 06947494bea31e536eba1d5c7d95791a9d2b5a99 Mon Sep 17 00:00:00 2001 From: Dmitry Eremin-Solenikov Date: Thu, 2 Jun 2011 15:54:08 +0400 Subject: mtd: drop ceiva map driver It's a Ceiva/Polaroid PhotoMax Digital Picture Frame. Support for it was commited before 2.6.12-rc2, current git contains no functional changes since it's start. Driver containing MTD support for that board was broken for some time already.
