Re: [PATCH 1/3] netfilter: nf_tables: avoid uninitialized variable warning

The newly added nft_range_eval() function handles the two possible
nft range operations, but as the compiler warning points out,
any unexpected value would lead to the 'mismatch' variable being
used without being initialized:

net/netfilter/nft_range.c: In function 'nft_range_eval':
net/netfilter/nft_range.c:45:5: error: 'mismatch' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This can be trivially avoided by added a 'default:' clause.

Applied this patch, I took Aaron's and Pai's patches instead.

Thanks anyway for following up on this issue Arnd.
