Subject: [PATCH 08/15] sysfs: kill unnecessary NULL pointer check in sysfs_release()
Date: Thu, 20 Sep 2007 16:05:10 +0900 [thread overview]
Message-ID: <11902719101962-git-send-email-htejun@gmail.com> (raw)
In-Reply-To: <11902719091692-git-send-email-htejun@gmail.com>
In sysfs_release(), sysfs_buffer pointed to by filp->private_data is
guaranteed to exist. Kill the unnecessary NULL check. This also
makes the code more consistent with the counterpart in fs/sysfs/bin.c.
