Subject: [PATCH] airo: remove unused variables len and dev and clean up formatting

From: Colin Ian King <colin.king@...onical.com>

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]
