Subject: [PATCH 0/3] mtd: maps: vmu-flash: Fix build and runtime errors 

Hi all,

This small series fixes build and runtime errors in the vmu-flash driver
(enabled by CONFIG_MTD_VMU) and the included maple.h. These changes were
verified on real Dreamcast hardware with a physical VMU. The VMU can now
be successfully probed, read and written with MTD tools like mtd_info and
mtd_debug. Previously, the driver failed to build or crashed during
probing.

	bash-5.3# mtdinfo /dev/mtd0
	mtd0
	Name:                           vmu2.1.0
	Type:                           mlc-nand
	Eraseblock size:                512 bytes
	Amount of eraseblocks:          256 (131072 bytes, 128.0 KiB)
	Minimum input/output unit size: 512 bytes
	Sub-page size:                  512 bytes
	Character device major/minor:   90:0
	Bad blocks are allowed:         true
	Device is writable:             true

Thanks,
Florian
