[ Upstream commit 8e91c2342351e0f5ef6c0a704384a7f6fc70c3b2 ]
Depending on the value of CONFIG_HZ, clang complains about a pointless comparison:
drivers/md/dm-integrity.c:4085:12: error: result of comparison of constant 42949672950 with expression of type 'unsigned int' is always false [-Werror,-Wtautological-constant-out-of-range-compare] if (val >= (uint64_t)UINT_MAX * 1000 / HZ) {
As the check remains useful for other configurations, shut up the warning by adding a second type cast to uint64_t.
