If 'p' is 0 for the software Diffie-Hellman implementation, then
dh_max_size() returns 0. In the case of KEYCTL_DH_COMPUTE, this causes

This patch series adds support for the RNG200 block found on the BCM7278 SoC.
This requires us to update the compatible string (and associated binding

Pointer members of an object with static storage duration, if not
explicitly initialized, will be initialized to a NULL pointer.
The crypto API checks if these pointers are not NULL before using them,
therefore we can safely remove these empty functions.

We are being passed an IV buffer from unknown origin, which may be
stack allocated and thus not safe for DMA. Allocate a DMA safe
