Subject: datapath: Use NULL instead of 0 in alloc_buckets().
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9099e1fc163534c0d66ba0d6b07889647485819b;p=openvswitch

datapath: Use NULL instead of 0 in alloc_buckets().

0 and NULL are the same but NULL has clearer semantics.  This has
no functional change.

Found with sparse.
