This patch had to be applied manually and with some fuzz when I applied
it to latest linus/master. There were no conflicts though and once I
applied it, I was able to test SPI flash on DA850 EVM successfully using it.

Acked-by: Sekhar Nori <nsekhar@...com>

I am hoping this patch can still go in v3.7. I realize we are in the
middle of the merge window though.

Thanks,
Sekhar
