Subject: staging: pi433: Remove unnecessary variable
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=48c80ccce63ff50f17b774131c9bd1cdb875d305;p=linux.git

staging: pi433: Remove unnecessary variable

The variable retval is assigned constant values twice, and can therefore
be replaced by its values.
