From 531060fc1989a438fbc2c3198f5057c40121ff50 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sat, 14 Jan 2012 10:49:44 +0000 Subject: [PATCH] FB: sa1100: combine RGB bitfield overrides into sa1100fb_mach_info Allow the sa1100fb_mach_info structure to carry the RGB bitfield overrides, rather than requiring them to be separately initialized in sa1100fb_get_machine_info().
