Date: Wed, 22 Jun 2011 19:00:03 -0700 Message-ID: <1308794413-11069-2-git-send-email-dirk.brandewie@gmail.com> References: <1308794413-11069-1-git-send-email-dirk.brandewie@gmail.com> Cc: Dirk Brandewie To: linux-kernel@vger.kernel.org, spi-devel-general@lists.sourceforge.net Return-path: In-Reply-To: <1308794413-11069-1-git-send-email-dirk.brandewie@gmail.com> Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-spi.vger.kernel.org From: Dirk Brandewie Expose the platform data structure for use by client drivers. ATM there are not any in-tree drivers using the driver (that I can find). This patch exposes the platform data needed for client drivers.
