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