Three main MTD fixes for 3.18:

Browse source 
* A regression from 3.16 which was noticed in 3.17. With the restructuring of
    the m25p80.c driver and the SPI NOR library framework, we omitted proper
    listing of the SPI device IDs. This means m25p80.c wouldn't auto-load
    (modprobe) properly when built as a module. For now, we duplicate the device
    IDs into both modules.
 
 * The OMAP / ELM modules were depending on an implicit link ordering. Use
   deferred probing so that the new link order (in 3.18-rc) can still allow for
   successful probing.
 
 * Fix suspend/resume support for LH28F640BF NOR flash
