[PATCH] staging: speakup: remove redundant variable l

[PATCH] staging: speakup: remove redundant variable l

[Colin King]

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

Linux, c'est comme le miel : c'est vachement bon mais ça attire les
mouches. En plus, ça colle aux doigts et on a du mal à s'en défaire.
