[PATCH 3.12 09/72] sfc: Fix memcpy() with const destination compiler warning.

From: Jiri Slaby
Date: Mon Nov 23 2015 - 08:08:33 EST

From: "David S. Miller" <davem@xxxxxxxxxxxxx>

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


commit 1d20a16062e771b6e26b843c0cde3b17c1146e00 upstream.

drivers/net/ethernet/sfc/selftest.c: In function âefx_iterate_stateâ:
drivers/net/ethernet/sfc/selftest.c:388:9: warning: passing argument 1 of âmemcpyâ discards âconstâ qualifier from pointer target type [-Wdiscarded-array-qualifiers]

This is because the msg[] member of struct efx_loopback_payload
is marked as 'const'. Remove that.
