Dear Mark,
included is a patch for you to apply to your ov511-2.28 driver.
It's basically a re-make of the in-kernel ov511 1.64 driver modification
wrt the remap_page_range -> remap_pfn_range API obsoleting (2.6.10)
and removal (2.6.11), applied to your 2.28 source.
(This should eliminate the unresolved symbol error for remap_page_range
for those who try out your 2.28 source against 2.6.11 or newer trees).
There is a bit of cut-and-paste involved in the page, but
it follows from the corresponding cut-and-paste in your
original code.
Tested on Linux asus3 2.6.11-gentoo-r9 #3 Wed Jun 8 21:41:40 IDT 2005 i686
Pentium III (Coppermine) GenuineIntel GNU/Linux, camera
chipset OV518/OV6630AF.
Please apply,
Vassilii
