Subject: [PATCH] Fix debugfs_create_dir's error checking method for arm/plat-omap
Date: Fri, 17 Oct 2008 17:23:02 +0800 [thread overview]
Message-ID: <48F85976.4070609@cn.fujitsu.com> (raw)
Hi,
debugfs_create_dir() returns NULL if an error occurs, returns -ENODEV
when debugfs is not enabled in the kernel.
