[PATCH 3/6] power: regulator: palmas: Cannot test unsigned for being negative

[Andrew Goodbody]

In palmas_smps_val and palmas_ldo_val hex is an unsigned variable being
assigned the return value from a function that returns int. Change hex
to be an int so that the following test for an error as a negative value
will work as expected.

This issue was found by Smatch.
