FS#551 - leftover printf's in the new opkg (since Feb 20)
User who did this - Mircea IONICĂ (mionica)

----------
note. problem seems to be in libopkg/opkg_upgrade.c, function pkg_hash_check_installed_pkg_helper() - it's a printf

also found some ptr=%p instances in pkg_depends.c, but those are opkg_msg() calls - and I haven't seen any of those
