From: "David S. Miller" <davem@davemloft.net> 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 ‘efx_iterate_state’: drivers/net/ethernet/sfc/selftest.c:388:9: warning: passing argument 1 of ‘memcpy’ discards ‘const’ 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. Signed-off-by: David S. Miller <davem@davemloft.net> Signed-off-by: Jiri Slaby <redacted> --- drivers/net/ethernet/sfc/selftest.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
