[61/70] usb: qcserial add missing errorpath kfrees
From: Greg KH
Date: Tue Apr 19 2011 - 16:19:54 EST
2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------
From: Steven Hardy <shardy@xxxxxxxxxx>
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
