This is a note to let you know that I've just added the patch titled
USB: iuu_phoenix: fix sysfs-attribute creation
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: iuu_phoenix: fix sysfs-attribute creation
Make sure sysfs attributes are created at port probe.
A recent patch ("USB: iuu_phoenix: fix port-data memory leak") removed
the sysfs-attribute creation by mistake.
