Hi,

spi_imx_devtype_data has already been driver private data.  There is
really no need to make a copy in spi_imx_data.  Instead, a reference
pointer works perfectly fine.
You obviously overlooked, that the copy is done on purpose to keep
only the data that is actually needed and discard everything else
after initialisation.
I did not overlook that, as I removed __devinitdata there.
But now you keep the whole array of which only one entry is being
used instead of only the used entry.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
