[PATCH] mm: memcontrol: use 'unsigned int' instead of bare 'unsigned'

[PATCH] mm: memcontrol: use 'unsigned int' instead of bare 'unsigned'

[Po-Sheng Lin]

Use 'unsigned int' instead of bare 'unsigned' for the order
parameters in split_page_memcg() and folio_split_memcg_refs(),
and for the new_refs local variable, for consistency with kernel
coding style guidelines.
