Subject: ext4: unsigned int compared against zero
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
commit fbbbbd2f28aec991f3fbc248df211550fbdfd58c upstream.
There are two cases where u32 variables n and err are being checked
for less than zero error values, the checks is always false because
the variables are not signed. Fix this by making the variables ints.
Addresses-Coverity: ("Unsigned compared against 0")
Fixes: 345c0dbf3a30 ("ext4: protect journal inode's blocks using block_validity")
