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).
