[PATCH] drivers: power: supply: Compress return logic into one line.

[Gustavo A. R. Silva]

Simplify return logic to avoid unnecessary variable assignments.
These issues were detected using Coccinelle and the following semantic patch:

@@
local idexpression ret;
expression e;
@@

-ret =
+return
     e;
-return ret;
