Subject: linux-next: build warning after merge of the crypto tree

Hi all,

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

security/keys/trusted-keys/trusted_caam.c: In function 'dump_options':
security/keys/trusted-keys/trusted_caam.c:37:20: note: the ABI of passing struct with a flexible array member has changed in GCC 4.4
   37 | static inline void dump_options(struct caam_pkey_info pkey_info)
      |                    ^~~~~~~~~~~~

Introduced by commit

  9eb25ca6c973 ("KEYS: trusted: caam based protected key")

I am not sure what to do about this.  It would be nice if we could
suppress the note as we do not support gcc 4.4 any more.  Otherwise,
I suspect that converting the pkey_info argument to a pointer will get
rid of the note.
