PATCH 1/1 JFFS on an MTDRAM device

Hi,

I needed the attached patch to allow a JFFS2 filesystem to be mounted using an MTDRAM driver (actually an SRAM chip).

Without it I get lots of warnings in jffs2_erase_callback: "Erase at 0x%08x finished, but state != MTD_ERASE_DONE. State is 0x%x instead."

Cheers,
Ian.
