mfd: ab8500-debugfs: Fix incompatible types in comparison expression issue
Smatch reports:
drivers/mfd/ab8500-debugfs.c:1804:20: error: incompatible types in comparison expression (different type sizes):
drivers/mfd/ab8500-debugfs.c:1804:20: unsigned int *
drivers/mfd/ab8500-debugfs.c:1804:20: unsigned long *
This is due to mixed types being compared in a min() comparison. Fix
this by treating values as signed and casting them to the same type
as the receiving variable.
