linux-next: build warning after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

fs/ubifs/dir.c: In function 'ubifs_readdir':
fs/ubifs/dir.c:629:13: warning: 'fstr_real_len' may be used uninitialized in this function [-Wmaybe-uninitialized]
fstr.len = fstr_real_len;
^

Introduced by commit

f4f61d2cc6d8 ("ubifs: Implement encrypted filenames")

This is a false positive because assignment and use are both protected by
"if (encrypted)".

I have no idea why this did not turn up earlier in my builds.
