From c213ddf330e29f9d141705444dc45683adbb99b0 Mon Sep 17 00:00:00 2001 From: Krzysztof Helt Date: Tue, 5 Aug 2008 13:01:26 -0700 Subject: [PATCH] fbcon: fix scrolling after logo is cleared If the 'clear' command is used on the frame buffer with a logo the upper area is filled by few lines but not scrolled anymore. Fix this by removing the protected area for the logo if any part of the logo is cleared.
