[PATCH v2 0/6] fix error checking in spi-nor read and write functions

[Michal Suchanek]

Hello,

This is update of the spi-nor patchset that implements error checking in SPI
transfers.

It's been pointed out that the first patch is too big so I split it into
smaller incremental patches.

With these patches writing to NOR flash connected to a SPI controller with
transfer size limitation should work properly.

Also when a transfer fails it should be now reported all the way to the
userspace rather than silently ignored.

Thanks

Michal
