[PATCH v3 0/6] Add error checking in spi-nor read and write

[Michal Suchanek <hramrach@gmail.com>]

Hello,

this is patchset which implements checking for SPI transfer errors in spi-nor.

With this you get an error rather than bunch of zeroes when a transfer fails
and you get correct operation on SPI controllers that truncate long transfers.

Since the only comment to the patchset was that it introduces a warning when
all patches are not applied I resend with this issue fixed.

Thanks

Michal
