From 46d1d5dd43e4d7c78f1fd6a5ee958d7b8a8626eb Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Sat, 5 Jan 2013 09:45:48 +0000 Subject: common/lcd.c: cleanup use of global variables lcd_color_fg and lcd_color_bg had to be declared in board specific code, but were not actually used there; in addition, we have getter / setter functions for these, which were not used either. Get rid of the global variables, and use the getter function where needed (so far no setter calls are needed).

Moving the check after the alignment block fixes this.
