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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tejun Heo <[email protected]>

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.
