Subject: drivers: staging: iio: accel: Removed unnecessary variable
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3194e14db920138f4a0a19a03cb4c26db9969445;p=openwrt%2Fstaging%2Fblogic.git

drivers: staging: iio: accel: Removed unnecessary variable

Variable len is used only to store the return value. Hence len 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;
