This patch fixes the following sparse warnings:
net/ipv4/ip_tunnel.c:245:53: warning: restricted __be16 degrades to integer
net/ipv4/ip_vti.c:321:19: warning: incorrect type in assignment (different base
types)
net/ipv4/ip_vti.c:321:19: expected restricted __be16 [addressable]
[assigned] [usertype] i_flags
net/ipv4/ip_vti.c:321:19: got int
net/ipv4/ip_vti.c:447:24: warning: incorrect type in assignment (different base
types)
net/ipv4/ip_vti.c:447:24: expected restricted __be16 [usertype] i_flags
net/ipv4/ip_vti.c:447:24: got int
Since VTI_ISVTI is always used with ip_tunnel_parm->i_flags (which is __be16),
we can __force cast VTI_ISVTI to __be16 in header file.
