[PATCH] staging: fbtft: fbtft-core: Fix last line displayed on fbcon

[Alexandru Ardelean]

From: Michael Hennerich <michael.hennerich@xxxxxxxxxx>

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.
