[PATCH v4 0/7] Add spi-nor SPI transfer error handling

[Michal Suchanek <hramrach@gmail.com>]

Hello,

with these patches SPI transfer errors are not silently ignored but rather
reported to spi-nor users.

This should prevent silently dropping data to the floor in cases when the SPI
transfer fails and the failure is detected.

It has been pointed out that MTD users do not handle the case when data is read
only partially so this version adds the last patch which handles this in
spi-nor.

Thanks

Michal
