When trying to build Wireshark, compilation fails with the following error:

packet-ess-template.c: In function `proto_register_ess':
packet-ess-template.c:174: warning: dereferencing type-punned pointer will
break strict-aliasing rules

Changing the relevant line in packet-ess-template.c from:

  uat_t *attributes_uat = uat_new("ESS Category Attributes",
                                  sizeof(ess_category_attributes_t),
                                  "ess_category_attributes",
                                  TRUE,
                                  (void**) &ess_category_attributes,

to:

  uat_t *attributes_uat = uat_new("ESS Category Attributes",
                                  sizeof(ess_category_attributes_t),
                                  "ess_category_attributes",
                                  TRUE,
                                  (void*) &ess_category_attributes,

fixes the error and compiles Wireshark successfully.
