Subject: [PATCH][next] efi/tpm: fix sanity check of unsigned tbl_size being less than zero
Date: Tue, 8 Oct 2019 11:01:53 +0100 [thread overview]
Message-ID: <20191008100153.8499-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Currently the check for tbl_size being less than zero is always false
because tbl_size is unsigned. Fix this by making it a signed int.
Addresses-Coverity: ("Unsigned compared against 0")
Fixes: e658c82be556 ("efi/tpm: Only set 'efi_tpm_final_log_size' after successful event log parsing")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
