+Subject: fec: fix possible NULL dereference in fec_mode_walk()
+
+Static analyzer (Svace) reported a possible null pointer dereference
+in fec_mode_walk(), where the 'name' pointer is passed to print_string()
+without checking for NULL.
+
+Although some callers check the return value of get_string(), others
+(e.g., walk_bitset()) do not. This patch adds an early NULL check
+to avoid dereferencing a null pointer.
+
+This resolves:
+DEREF_OF_NULL.EX.COND: json_print.c:142 via fec.c
+
+Found by Svace static analysis tool.
