Subject: [10/67] SCSI: fcoe: Fix preempt count leak in fcoe_filter_frames()

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Thomas Gleixner <tglx@...utronix.de>

commit 7e1e7ead88dff75b11b86ee0d5232c4591be1326 upstream.

The error exit path leaks preempt count. Add the missing put_cpu().
