Subject: drivers: staging: iio: meter: Removed unnecessary variable
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=07f83131e5b5d309dc8dd41911b66d3ce4c99323;p=deliverable%2Flinux.git

drivers: staging: iio: meter: Removed unnecessary variable

Variable ret is used only to store the return value. Hence ret is
removed and the return statement modified. Coccinelle was used to
detect such removable variables:

@rule1@
identifier ret;
expression e;
@@

-ret =
+return
           e;
-return ret;
