| |
To move the list iterator variable into the list_for_each_entry_*() macro in the future it should be avoided to use the list iterator variable after the loop body.
To *never* use the list iterator variable after the loop it was concluded to use a separate iterator variable instead of a found boolean [1].
This removes the need to use a found variable and simply checking if the variable was set, can determine if the break/goto was hit.
