From ba5fd193f4fd35e5e1771de15cc1aba11d19590d Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 14 Jan 2012 12:32:14 +0000 Subject: [PATCH] FB: sa1100: use inf members directly Now that the LCD information is available while the driver is loaded, we don't need to cache that information into our driver private data structure. Get rid of it.
