Variable entry holds result of jumbo_frm callback. It can be negative, so the variable should be signed. The patch changes also type of related first_entry variable to make code compact and coherent.
The problem has been detected using patch scripts/coccinelle/tests/unsigned_lesser_than_zero.cocci.
