patch "USB: ohci-sm501: Add missed iounmap() in remove" added to usb-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    USB: ohci-sm501: Add missed iounmap() in remove

to my usb git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: USB: ohci-sm501: Add missed iounmap() in remove

This driver misses calling iounmap() in remove to undo the ioremap()
called in probe.
Add the missed call to fix it.
