And it seems that I don't know how to spell my own name anymore! :)
If you decide for this patch please let me know, so we can fix while pushing to drm-misc-fixes or tell me to send a v2.
I'm not entirely sure about the limits we should use here on ARM based driver, but apparently the entry and limit are inverted and UINT_MAX cannot be used directly there.
So let's at least for now fix this compilation issue on a compilation only driver:
I ended up writing this as well and squashing it into the merge into drm-next.
Thanks, Dave.
