Hi All,

The builds of arm64 allmodconfig with clang have failed to build
next-20220914 with the error:

fs/f2fs/recovery.c:509:17: error: variable 'ino' is uninitialized when used here [-Werror,-Wuninitialized]
                        ofs_in_node, ino, nid, max_addrs);
                                     ^~~
fs/f2fs/f2fs.h:2376:35: note: expanded from macro 'f2fs_err'
        f2fs_printk(sbi, KERN_ERR fmt, ##__VA_ARGS__)
                                         ^~~~~~~~~~~
fs/f2fs/recovery.c:475:11: note: initialize the variable 'ino' to silence this warning
        nid_t ino, nid;
                 ^
                  = 0
1 error generated.

git bisect pointed to 64c11570d64d ("f2fs: fix to do sanity check on summary info").

I will be happy to test any patch or provide any extra log if needed.
