Subject[PATCH] staging: speakup: remove redundant variable l
Date
From: Colin Ian King <colin.king@canonical.com>

Variable l is being assigned but is never used hence it is redundant
and can be removed.

Cleans up clang warning:
warning: variable 'l' set but not used [-Wunused-but-set-variable

Signed-off-by: Colin Ian King <colin.king@canonical.com>
