mtd: nand: pxa3xx: Fix registered MTD name
In a recent commit: commit f455578dd961087a5cf94730d9f6489bb1d355f0 Author: Ezequiel Garcia <ezequiel.garcia@free-electrons.com> Date: Mon Aug 12 14:14:53 2013 -0300 mtd: nand: pxa3xx: Remove hardcoded mtd name There's no advantage in using a hardcoded name for the mtd device. Instead use the provided by the platform_device. The MTD name was changed to use the one provided by the platform_device. However, this can be problematic as some users want to set partitions using the kernel parameter 'mtdparts', where the name is needed. Therefore, to avoid regressions in users relying in 'mtdparts' we revert the change and use the previous one 'pxa3xx_nand-0'. While at it, let's put a big comment and prevent this change from happening ever again.
