[ 106/184] USB: serial: Fix memory leak in sierra_release()

[Willy Tarreau]

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

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

From: Lennart Sorensen <lsorense@xxxxxxxxxxxxxxxxxxx>

commit f7bc5051667b74c3861f79eed98c60d5c3b883f7 upstream.

I found a memory leak in sierra_release() (well sierra_probe() I guess)
that looses 8 bytes each time the driver releases a device.
