time, s390: Get rid of compile warning
"s390: Use direct ktime path for s390 clockevent device" in linux-next
introduces this compile warning:
arch/s390/kernel/time.c: In function 's390_next_ktime':
arch/s390/kernel/time.c:118:2: warning:
comparison of distinct pointer types lacks a cast [enabled by default]
Just use a u64 instead of an s64 variable. This is not a problem since it
will always contain a positive value.
