[PATCH] Revert "mtd: core: always create master device"

[Michael Walle]

Hi,

> The idea behind this patch was to always let a "master" mtd device
> available to anchor runtime PM. Historically, there was no mtd device
> representing the whole storage as soon as partitions were coming into
> play. The introduction of CONFIG_MTD_PARTITIONED_MASTER allowed to keep
> this "master" device, but was not enabled by default to avoid breaking
> existing users (otherwise the mtd device numbering would be totally
> messed up with an off by 1, at least).
> 
> The approach of adding an mtd_master class on top of partitioned mtd
> devices is breaking the mtd core in many creative ways, so better think
> again this approach and revert the faulty changes for now.
> 
> This reverts commit 0aa7b390fc40a871267a2328bbbefca8b37ad307.

Should this have a Fixes tag?
