ioremap balanced with iounmap for drivers/mtd subsystem
ioremap must be balanced by an iounmap and failing to do so can result in a memory leak. Tested (compilation only) with: - allmodconfig - Modifying drivers/mtd/maps/Kconfig and drivers/mtd/nand/Kconfig to make sure that the changed file is compiling without warning Signed-off-by: Amol Lad <amol@verismonetworks.com> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
