Using the new find_closest() macro can result in the following sparse
warnings.

drivers/hwmon/lm85.c:194:16: warning:
                incorrect type in initializer (different modifiers)
drivers/hwmon/lm85.c:194:16:    expected int *__fc_a
drivers/hwmon/lm85.c:194:16:    got int static const [toplevel] *<noident>
drivers/hwmon/lm85.c:210:16: warning:
                incorrect type in initializer (different modifiers)
drivers/hwmon/lm85.c:210:16:    expected int *__fc_a
drivers/hwmon/lm85.c:210:16:    got int const *map

This is because the array passed to find_closest() will typically be
declared as array of constants, but the macro declares a non-constant
pointer to it.
