Subject: [PATCH 1/1] MD: dm-log, fix cn_ulog_callback declaration

The third parameter of cn_add_callback accepts functions with
void *()(struct cn_msg *)
prototype. Change cn_ulog_callback to match it by removing void *
and adding struct cn_msg * directly.

It's introduced by commit:
connector: make callback argument type explicit
