Subject: [PATCH 59/75] sysfs: kill unnecessary NULL pointer check in sysfs_release()

From: Tejun Heo <htejun@...il.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.
