[PATCH 3/7] Char: cyclades, fix unused variable

From: Jiri Slaby
Date: Wed Mar 23 2011 - 04:50:17 EST


drivers/tty/cyclades.c:1454:2: warning: Value stored to 'channel' is never read
channel = info->line - card->first_line;
^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix it by moving it to the appropriate debug section where it is used.
