Hi
This patch crashes my system, when issue suspend to ram, the kernel
crashes mtd_cls_suspend when the mtd device is mtdXro, the problem is
the the mtdXro devices are of mtd_class, and the suspend function of
this class assumes that the "dev" is contained in mtd_into structure
(dev_to_mtd(dev)), but, the mtdXro device created using
device_create() so the dev is not contained in valid mtd_info
structure.
