From: Dmitry Popov Date: Wed, 11 Jun 2014 11:09:14 +0000 (+0400) Subject: ip_vti: fix sparse warnings for VTI_ISVTI X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=efd0f11d85e16d375dddeb77e8e78f43c67c5b13;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ip_vti: fix sparse warnings for VTI_ISVTI 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.
