Hello,

I am working with half-broken SPI drivers which sometimes fail and spi-nor
completely ignores that leading to silent data corruption.

With these patches I get actual I/O errors when something fails.

Testing on different hardware would be appreciated, especially fsl-qspi.

I don't recall any comment on these patches so I am resending them separately.

Thanks

Michal
