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.

The ESP code has been updated to generate a completely linear AD SG list. This unfortunately broke authencesn which expects the AD to be divided into at least three parts. This patch fixes it to cope with the new format. Later we will fix it properly to accept arbitrary input and not rely on the input being linear as part of the AEAD conversion.

This patch converts picoxcell to the new AEAD interface. IV generation has been removed since it's equivalent to a software implementation. As picoxcell cannot handle SG lists longer than 16 elements, this patch has made the software fallback mandatory. If an SG list comes in that exceeds the limit, we will simply use the fallback.

The encap shared descriptor was changed to use the new IV convention. In the process some commands were shifted, making the output length zero, caam effectively writing garbage in dst. While here, update the decap descriptor to execute the "write" commands before the "read"s (as it previously was). This makes sure the input fifo is drained before becoming full.

Return success instead of error if compression succeeds but the output is larger than the input. It's unlikely that the caller will use the compressed data since it's larger than the original uncompressed data, but there was no error and returning an error code is incorrect. Further, for testing small input buffers, the output is likely to be larger than the input and success needs to be returned to verify the test.
