From: root <r...@fecusia.(none)> This replace all instances in the i2c busses tree of res->end - res->start + 1 with the handy macro resource_size(res) from ioport.h (coming in from platform_device.h).
This was created with a simple sed -i -e 's/\([a-z]*\)->end *- *[a-z]*->start *+ *1/resource_size(\1)/g' Then manually replacing the PXA redefiniton of the same kind of macro manually. Recompiled some ARM defconfigs I could find to make a rough test so it shouldn't break anything, though I couldn't see exactly which configs you need for all the drivers.
