Missing #include <linux/compat.h>
After adding it the error goes away.

Hi everyone,
I can send a fixup patch for this error if needed. Could someone guide
me on whether I should amend the original patch-set and send a v9
patchset or if there's another way to handle this without sending a v9
patchset?
Thanks,
Abhishek.

I think Andrew already fixed it up (I saw an email flying by but I'll
double-check).
