Subject: [61/70] usb: qcserial add missing errorpath kfrees

2.6.38-stable review patch.  If anyone has any objections, please let us know.

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

From: Steven Hardy <shardy@...hat.com>

commit cb62d65f966146a39fdde548cb474dacf1d00fa5 upstream.

There are two -ENODEV error paths in qcprobe where the allocated private
data is not freed, this patch adds the two missing kfrees to avoid
leaking memory on the error path
