Subject: net: Use a more standard macro for INET_ADDR_COOKIE
X-Git-Tag: omap-for-v3.16/fixes-against-rc1~36^2~225
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c7228317441f4dee5e5916e30300dd8c61f75af7;p=pandora-kernel.git

net: Use a more standard macro for INET_ADDR_COOKIE

Missing a colon on definition use is a bit odd so
change the macro for the 32 bit case to declare an
__attribute__((unused)) and __deprecated variable.

The __deprecated attribute will cause gcc to emit
an error if the variable is actually used.
