wimax: fix duplicate initializer warning
gcc -Wextra points out multiple fields that use the same index '1' in the wimax_gnl_policy definition: net/wimax/stack.c:393:29: warning: initialized field overwritten [-Woverride-init] net/wimax/stack.c:397:28: warning: initialized field overwritten [-Woverride-init] net/wimax/stack.c:398:26: warning: initialized field overwritten [-Woverride-init] This seems to work since all four use the same NLA_U32 value, but it still appears to be wrong. In addition, there is no intializer for WIMAX_GNL_MSG_PIPE_NAME, which uses the same index '2' as WIMAX_GNL_RFKILL_STATE. Johannes already changed this twice to improve it, but I don't think there is a good solution, so try to work around it by using a numeric index and adding comments. Fixes: 3b0f31f2b8c9 ("genetlink: make policy common to family") Fixes: b61a5eea5904 ("wimax: use genl_register_family_with_ops()") Acked-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
