[Andi Kleen]

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Kashyap, Desai <kashyap.desai@xxxxxxx>

commit 84857c8bf83e8aa87afc57d2956ba01f11d82386 upstream.

Added missing release callback for file_operations mptctl_fops.
Without release callback there will be never freed. It remains on
mptctl's eent list even after the file is closed and released.

Relavent RHEL bugzilla is 660871
