Subject: [PATCH 0/5] fix missing break in list_or_each_entry

Instead of exiting the loop as expected when an entry is found, the
list_for_each_entry() continues until the traversal is complete. It
could lead to invalid reference or set 'is_*' flags mistakely.

To fix this, when an entry is found, add a break to exit the loop.
