Subject: [PATCH 08/16] hwmon: max6639: Fix type incompatibility with non-macro find_closest

The freq_table array was previously declared as unsigned int but used
with find_closest(). With find_closest() now implemented as a function
taking signed int parameters instead of a macro, passing unsigned arrays
causes type incompatibility errors. This patch changes the array type from
unsigned int to int to ensure compatibility with the function signature and
prevent compilation errors.
