Marko Kohtala 043f0229f4 video: ssd1307fb: Start page range at page_offset
[ Upstream commit dd9782834d ]

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.
