Subject: [patch] cifs: update a check for NULL function pointer
Date: Tue, 26 Aug 2014 07:38:03 +0000	[thread overview]
Message-ID: <20140826073802.GA31076@mwanda> (raw)

We changed the function call from ->close() to ->close_dir() so we
should update the test for NULL as well.

Both of them probably work, but my static checker complains when we have
a check for a NULL function pointer and then immediately call a
different function pointer.  This is a common cut and paste error.
