Comment (by wonderboymusic):

 In [changeset:"28304"]:
 {{{
 #!CommitTicketReference repository="" revision="28304"
 In `wp-admin/includes/update.php`, remove dead code:

 * In `get_core_checksums()`, `$return` is set and never used.
 * In `core_update_footer()`, `break` is unnecessary and unreachable after
 `return`.
 * In `get_theme_updates()`, `$themes` is set and never used.
 * In `wp_theme_update_row()`, `$theme_name` is the only user of
 `$themes_allowedtags`... neither are used.

 See #27882.
