clang becomes confused due to the comparison to NULL in a integer constant
expression context:
>> drivers/infiniband/hw/qib/qib_sysfs.c:413:1: error: static_assert expression is not an integral constant expression
QIB_DIAGC_ATTR(rc_resends);
^~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/infiniband/hw/qib/qib_sysfs.c:406:16: note: expanded from macro 'QIB_DIAGC_ATTR'
static_assert(&((struct qib_ibport *)0)->rvp.n_##N != (u64 *)NULL); \
Nathan found __same_type that solves this problem nicely, so use it instead.
