Hi Kamalesh

I know another patch is circulating, but please try the following.
diff --git a/drivers/net/sis190.c b/drivers/net/sis190.c
index b570402..0a5e024 100644

It is the better fix if you can confirm it working.
The section conflict issued by gcc happens because we try to
mix const and non-const data in the same section.
