Sorry for the "1/3" -- there's only this one patch.
The other two would have been resends of patches that
never got acked, but do seem to be in the MTD git tree.

However I noticed that this patch will have a problem
applying against that MTD git ... the m25p80 driver
got taught how to use two of the "extended" JEDEC ID
bytes provided by some vendors, so the initializers here
are all missing an extra "u16" value following the JEDEC
code.  Swap in a 0 for the Macronix part and all should
be OK ...
