  11 commit 1d20a16062e771b6e26b843c0cde3b17c1146e00 upstream.
  12
  13 drivers/net/ethernet/sfc/selftest.c: In function ‘efx_iterate_state’:
  14 drivers/net/ethernet/sfc/selftest.c:388:9: warning: passing argument 1 of ‘memcpy’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-array-qualifiers]
  15
  16 This is because the msg[] member of struct efx_loopback_payload
  17 is marked as 'const'.  Remove that.
