Subject: [PATCH] mtd: m25p80,spi-nor: Fix module aliases for m25p80
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.
