From c7ef5e285c842bdca1121512967400443e565456 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 11 Jul 2022 17:50:27 +0200 Subject: [PATCH] video: fbdev: atari: Fix inverse handling Currently, the "inverse" option does not do anything, as it just sets a flag, which is further unused. Fix this by calling fb_invert_cmaps() instead, like other drivers do. As this only affects the console colormap, this does not affect X. Update the documentation to match the actual behavior.
