I was going to recommend a better $subject line, but now I see why it's
vague. :(  I would recommend breaking this patch up into three:

  hwrng: amd - Access hardware via ioread32/iowrite32
  hwrng: amd - Replace global variable with private struct
  hwrng: amd - Convert to new hwrng read() API

thx,

Jason.
