Patch 1 check for return value of more functions. If real HW or 
software emulated HW (in qemu) does not support e.g. aes then 
kernel show oops message, because kernel does not check return 
values and try to touch non-existent HW. So I think patch 1 is 
really fix. In my opinion if something can fail, then kernel 
should check if it failed. And not expect that function call 
always pass.
