From 07df1c4fea1474ae6db2c8554d2915cf5cf81369 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Thu, 4 Dec 2008 11:14:11 +0800 Subject: [PATCH] [ARM] pxafb: small cleanup of the smart panel code Group smart panel related code in a more compact fasion, avoid abused usage of #ifdef .. #endif. Also fix the incorrect condition in pxafb_smart_init() to decide if it is a smart panel or not.
