Dan Carpenter 1f5b07f5dd crypto: marvell/octeontx - Fix a potential NULL dereference 
Smatch reports that:

    drivers/crypto/marvell/octeontx/otx_cptvf_algs.c:132 otx_cpt_aead_callback()
    warn: variable dereferenced before check 'cpt_info' (see line 121)

This function is called from process_pending_queue() as:

drivers/crypto/marvell/octeontx/otx_cptvf_reqmgr.c
   599                  /*
   600                   * Call callback after current pending entry has been
   601                   * processed, we don't do it if the callback pointer is
   602                   * invalid.
   603                   */
   604                  if (callback)
   605                          callback(res_code, areq, cpt_info);

It does appear to me that "cpt_info" can be NULL so this could lead to
a NULL dereference.

Fixes: 10b4f09491 ("crypto: marvell - add the Virtual Function driver for CPT")
