From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
The current comparison of entry < 0 will never be true since entry is an
unsigned integer. Make entry an int to ensure -ve error return values
from the call to jumbo_frm are correctly being caught.
Detected by CoverityScan, CID#1238760 ("Macro compares unsigned to 0")
