Check for 'int \*id' in the pernet_operations struct fails for some later versions of kernels as the declaration is now 'int * const id'. Kernel Commit 768e4bb6a75e3c6a034df7c67edac20bd222857e changed the variable declaration that ipset uses to ensure presence of the pernet ops id. Modify the pattern match to include both the newer change while still supporting the original declaration.
