Subject[PATCH 3.18 023/120] uwb: hwa-rc: fix memory leak at probe
Date
3.18-stable review patch.  If anyone has any objections, please let me know.

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

From: Anton Vasilyev <vasilyev@ispras.ru>

[ Upstream commit 11b71782c1d10d9bccc31825cf84291cd7588a1e ]

hwarc_probe() allocates memory for hwarc, but does not free it
if uwb_rc_add() or hwarc_get_version() fail.

Found by Linux Driver Verification project (linuxtesting.org).
