From 91d6f911b348dcb8e22d87913f4a0f52e646e990 Mon Sep 17 00:00:00 2001 From: Michael Hennerich Date: Fri, 11 Oct 2019 14:24:41 +0300 Subject: [PATCH] staging: fbtft: fbtft-core: Fix last line displayed on fbcon For the special case when fbtft_mkdirty() is called with with -1 for the y coordinate, the height is truncated by 1. This isn't required, and causes the last line to not update.
