Hello Greg,
I've posted an identical patch for udlfb too. Could you consider adding
that patch too?
Uhm, that won't work. Things have to reach mainline before they are
applied to stable. If Bernie does not react, please resend your patch as
your initial mail didn't reach the fbdev-list for some reason nor my
private inbox.
I've resend the patch for udlfb(to lkml, fbdev and Bernie). See
https://lkml.org/lkml/2012/8/14/36
The reason that I didn't send the patch for udlfb to the mailinglist
fbdev was that there wasn't an entry in MAINTAINERS for udlfb, therefor
I've send that patch only to the LKML and Bernie.
Regards,
Alexander

Subject: video/smscufx: fix line counting in fb_write
From: Alexander Holler <[email protected]>
commit 2fe2d9f47cfe1a3e66e7d087368b3d7155b04c15 upstream.
Line 0 and 1 were both written to line 0 (on the display) and all
subsequent
lines had an offset of -1. The result was that the last line on the
display
was never overwritten by writes to /dev/fbN.
The origin of this bug seems to have been udlfb.
