Message-ID: <20130409070659.GA5919@udknight>
Date: Tue, 9 Apr 2013 15:07:00 +0800
From: Wang YanQing <udknight@...il.com>
To: jkosina@...e.cz
Cc: linux-kernel@...r.kernel.org, trivial@...nel.org
Subject: [PATCH][TRIVIAL]drivers: Fix a class of compiler warnings
Fix the warnings look like below:
/linux/drivers/dma/timb_dma.c:801: warning: 'td_remove' defined but not used
I get the warning above when I compile 3.8.6 kernel,
then I fix it and others' same issue in kernel with
the help of perl, then I review and check the changes
one by one.
