Subject[PATCH] mtd: omap2: Release memory region in .remove function
Date
When the driver is compiled as module, it's not possible to unload and
reload the driver again:

omap2-nand: probe of omap2-nand.0 failed with error -16

This patch fixes the problem because it releases the memory region, so
that it can be requested again.
