[PATCH] crypto/dpaa2_sec: remove iova conversion for fle address

[Shreyansh Jain]

From: Hemant Agrawal <hemant.agrawal@nxp.com>

fle is already in virtual addressing mode - no need to perform
address conversion for it.

No worries. Actually, gcc 32 bits is broken:

drivers/crypto/dpaa2_sec/dpaa2_sec_dpseci.c:1264:7:
error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
  op = (struct rte_crypto_op *)DPAA2_GET_FLE_ADDR((fle - 1));

Is this PMD supposed to be compatible for 32-bit targets?

Thanks,

Oh! This is bad. I will send you an update on this in a few minutes.
Ideally, the code was written for 64bit in mind - though, it should 
still be able to work (at least compile) for 32 bit.

I have sent the v2 but I observe that the patchwork for v1 states 
'accepted' - not sure if I can change that back to 'superseded'.

If you have already applied and issued the pull request for next (and 
you won't be changing it), I will send a fix against that.
