Acks/tested-by's are still welcome. I plan to send this out in 3.18 (maybe for -rc2) if things look good. Brian

m25p80's device ID table is now spi_nor_ids, defined in spi-nor. The MODULE_DEVICE_TABLE() macro doesn't work with extern definitions, but its use was also removed at the same time. Now if m25p80 is built as a module it doesn't get the necessary aliases to be loaded automatically. A clean solution to this will involve defining the list of device IDs in spi-nor.h and removing struct spi_device_id from the spi-nor API, but this is quite a large change. As a quick fix suitable for stable, copy the device IDs back into m25p80.
