Could you please help
The drbg_state_ops structures are never modified, so declare them as const.
Done with the help of Coccinelle.

Threaded interrupts can perform the function of the tasklet, and much
more safely too - without races when trying to take the tasklet and
interrupt down on device removal.
With the old code, there is a window where we call tasklet_kill(). If
the interrupt handler happens to be running on a differ
Rather than giving the descriptor as hw_desc[0], give it's real size.
All places where we allocate an ahash_edesc incorporate DESC_JOB_IO_LEN
bytes of job descriptor.

Ensure that we clean up allocations and DMA mappings after encountering
an error rather than just giving up and leaking memory and resources.

Mark the hardware descriptor as being cache line aligned; on DMA
incoherent architectures, the hardware descriptor should sit in a
separate cache line from the CPU accessed data to avoid polluting
the caches.

Strictly, dma_map_sg() may coalesce SG entries, but in practise on iMX
hardware, this will never happen. However, dma_map_sg() can fail, and
we completely fail to check its return value. So, fix this properly.
Arrange the code to map the scatterlist early, so we know how many

Since the extended descriptor includes the hardware descriptor, and the
sec4 scatterlist immediately follows this, we can declare it as a array
at the very end of the extended descriptor. This allows us to get rid
of an initialiser for every site where we allocate an extended
descriptor.

caamhash contains this weird code:
src_nents = sg_count(req->src, req->nbytes);
dma_map_sg(jrdev, req->src, src_nents ? : 1, DMA_TO_DEVICE);
...
edesc->src_nents = src_nents;
sg_count() returns zero when sg_nents_for_len() returns zero or one.
This means we don't n
Here are further imx-caam updates that I've had since before the
previous merge window. Please review and (I guess) if Freescale
folk can provide acks etc that would be nice. Thanks.
