Subject: [PATCH 4.8 76/96] i40iw: Use correct src address in memcpy to rdma stats counters

4.8-stable review patch.  If anyone has any objections, please let me know.

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

From: Shiraz Saleem <shiraz.saleem@...el.com>

commit 91c42b72f8e8b45961ff05a05009b644e6316ca2 upstream.

hw_stats is a pointer to i40_iw_dev_stats struct in i40iw_get_hw_stats().
Use hw_stats and not &hw_stats in the memcpy to copy the i40iw device stats
data into rdma_hw_stats counters.

Fixes: b40f4757daa1 ("IB/core: Make device counter infrastructure dynamic")
