Hmm, I was wrong, it is not possible (from first view).
Here is a sequence of events to setup a crypto session:
1. user calls setkey, which results in tfm. It is possible to get a
context from tfm. Context can be initialized via cra_init() callback in
registered algorithm. But there is no way to provide a private pointer
into that callback. So, there is no way to provide a pointer to
hifn_device and thus tfm context can not find a hardware device to setup
this session.
Herbert, could you please elaborate how to provide a private pointer
into cra_init without searching via static lists of all devices?
