An implicit instance of module.h leaked back into existence and was masking the fact that these drivers weren't calling out the include for itself. Fix the drivers before we remove the implicit include path via net/netprio_cgroup.h file. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
