From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Variables iflag, mask and serial are being assigned but ar never used
hence are redundant and can be removed.
Cleans up clang warnings:
warning: variable 'iflag' set but not used [-Wunused-but-set-variable]
warning: variable 'mask' set but not used [-Wunused-but-set-variable]
warning: variable 'serial' set but not used [-Wunused-but-set-variable]
