In kernel 5.4, support has been added for reading MTD devices via the nvmem API. For this the mtd devices are registered as read-only NVMEM providers under sysfs with the same name as the flash partition label property. So if flash partition label property of multiple flash devices are identical then the second mtd device fails to get registered as a NVMEM provider. This patch fixes the issue by having different label property for different flashes.
