The dwmac-socfpga.c conflict was a case of a bug fix overlapping
changes in net-next to handle an error pointer differently.

@ -62,11 +62,10 @@ Socket Interface
================
AF_RDS, PF_RDS, SOL_RDS
These constants haven't been assigned yet, because RDS isn't in
mainline yet. Currently, the kernel module assigns some constant
and publishes it to user space through two sysctl files
/proc/sys/net/rds/pf_rds
/proc/sys/net/rds/sol_rds
AF_RDS and PF_RDS are the domain type to be used with socket(2)
to create RDS sockets. SOL_RDS is the socket-level to be used
with setsockopt(2) and getsockopt(2) for RDS specific socket
options.
fd = socket(PF_RDS, SOCK_SEQPACKET, 0);
This creates a new, unbound RDS socket.
