Absolutely, physmasp subdevices are never initialized/registered, so you can't call any of the mtd helpers taking the suspend lock on those. I guess it'd be better to call mtd_suspend/resume() on the concat device in though:
static void physmap_flash_shutdown(struct platform_device *dev) { struct physmap_flash_info *info = platform_get_drvdata(dev);
mtd_suspend(info->cmtd); }
