[PATCH] regulator: tps80031: remove redundant assignment to variables ret and val

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variables ret and val are being initialized with values that are
never read and are being updated later with a new value.  The
initializations are redundant and can be removed.

Addresses-Coverity: ("Unused value")
