Subject: sfc: Fix memcpy() with const destination compiler warning.
X-Git-Tag: firefly_0821_release~176^2~1941^2~3
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=1d20a16062e771b6e26b843c0cde3b17c1146e00;p=firefly-linux-kernel-4.4.55.git

sfc: Fix memcpy() with const destination compiler warning.

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.
