Currently ret is assigned to zero and the following statement checks
if it is non-zero. This check is redundant and can be removed
Addresses-Coverity: ("Logically dead code")
Fixes: 5069185fc18e ("power: supply: bq25980: Add support for the BQ259xx family")

then at the end of the function it could be changed from "return ret;"
to "return 0;"
