Series [v3,01/20] diff: use hashmap_entry_init on moved_entry.ent | expand

Commit Message

Eric Wong Oct. 6, 2019, 11:30 p.m. UTC 
C compilers do type checking to make life easier for us.  So
rely on that and update all hashmap_entry_init callers to take
"struct hashmap_entry *" to avoid future bugs while improving
safety and readability.
