   Because Mason doesn't want to develop the HyperFlash driver (or even move his code
in preparation to this driver being developed). I must develop this driver, and I'd
like to avoid the extra churn of mving the code between the MFD and SPI drivers.

   I was providing the feedback during these 13 revisions... unfortunately, it wasn't
fully considered.
