The data structure of_match_ptr() protects is always compiled in.
Hence of_match_ptr() is not needed.

There is a typo here.  "dev->hw_link[]" is an array, not a pointer, so
the check is nonsense.  We should be checking recently allocated
"dev->hw_link[0]" instead.

The sahara crypto driver has an incorrect MODULE_DEVICE_TABLE, which
prevents us from actually building this driver as a loadable module.

sahara_dt_ids is a of_device_id array, so we have to use
MODULE_DEVICE_TABLE(of, ...).

SAHARA2 HW module is included in the i.MX27 SoC from
Freescale. It is capable of performing cipher algorithms
such as AES, 3DES..., hashing and RNG too.

This driver provides support for AES-CBC and AES-ECB
by now.
