Subject: [patch 5/9] [PATCH] lcs: get rid of compile warning

From: [email-masked]
Date: Tue, 10 May 2011 13:50:18 +0200

From: Heiko Carstens <[email-masked]>

-Wunused-but-set-variable generates a compile warning for lcs' tasklet
function. Invoked functions contain already error handling; thus
additional return code checking is not needed here.
