Variables len and dev assigned values but are never used hence they
are redundant and can be removed. Also add in white space in for-loop
and remove some { } braces on if statement.
Cleans up clang warnings:
warning: variable 'len' set but not used [-Wunused-but-set-variable]
warning: variable 'dev' set but not used [-Wunused-but-set-variable]
