Subject: usb: qcserial add missing errorpath kfrees
From: Steven Hardy <[email protected]>
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
