As IV generators are now standalone AEAD transforms, we no longer
need to use the crypto_lookup_aead call.

Variable 'ret' is only used for returning the value 0.
We can make it simpler and just return 0 instead.
The semantic patch that makes this change is available

On sun6i and later platforms, the reset control is split out of the
clock gates. Add support for an optional reset control.

Later Allwinner SoCs split out the reset controls for individual modules
out of the clock gate controls. The "Security System" crypto engine is
no different.

CTR hardware implementation does not match with kernel spec causing a counter bug
where just low 8 bytes are used for counter, when should be all 16bytes.
Since we already have other counter modes working according with specs
not worth to keep CTR itself on NX.

The PCI capabilities list for Intel DH895xCC VFs (device id 0x0443) with
QuickAssist Technology is prematurely terminated in hardware.
Workaround the issue by hard-coding the known expected next capability
pointer and saving the PCIE cap into internal buffer.

The probe error path for this driver, for all intents and purposes,
is the talitos_remove() function due to the common "goto err_out".
Without this patch applied, talitos_remove() will panic under these
two conditions:
1. If the RNG device hasn't been registered via
talitos_register_rng() prior to entry into talitos_remove(),
then the attempt to unregister the RNG "device" will cause a panic.
2. If the priv->chan array has not been allocated prior to entry
into talitos_remove(), then the per-channel FIFO cleanup will panic
because of the dereference of that NULL "array".
Both of the above scenarios occur if talitos_probe_irq() fails.
This patch resolves issue #1 by introducing a boolean to mask the
hwrng_unregister() call in talitos_unregister_rng() if RNG device
registration was unsuccessful.
It resolves issue #2 by checking that priv->chan is not NULL in the
per-channel FIFO cleanup for loop.
