Subject: [PATCH 4.4 01/36] video: ssd1307fb: Start page range at page_offset
Date: Sun, 6 Oct 2019 19:18:43 +0200 [thread overview]
Message-ID: <20191006171041.501430611@linuxfoundation.org> (raw)
In-Reply-To: <20191006171038.266461022@linuxfoundation.org>
From: Marko Kohtala <marko.kohtala@okoko.fi>
[ Upstream commit dd9782834dd9dde3624ff1acea8859f3d3e792d4 ]
The page_offset was only applied to the end of the page range. This caused
the display updates to cause a scrolling effect on the display because the
amount of data written to the display did not match the range display
expected.
Fixes: 301bc0675b67 ("video: ssd1307fb: Make use of horizontal addressing mode")
