+Subject: efi/tpm: Fix sanity check of unsigned tbl_size being less than zero
+
+From: Colin Ian King <colin.king@canonical.com>
+
+commit be59d57f98065af0b8472f66a0a969207b168680 upstream.
+
+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")
