From e5bdf248c24feab41fc7b8245e37277f1ae60e3e Mon Sep 17 00:00:00 2001

Subject: [PATCH] vga: fix region calculation
Typically the scanline length and the line offset are identical. But
in case they are not our calculation for region_end is incorrect. Using
line_offset is fine for all scanlines, except the last one where we have
to use the actual scanline length.
