Sure, that's fine with me if you want to make it a platform device, but note that a platform device doesn't have a minor associated with it, you will have to still have your existing srom_class and the rest. Right now you aren't creating any real "devices" in the kernel, other than the one you use for your minor number, which is not a "real" device. struct srom_dev should be a platform device and then this will get "easier" overall, sorry I missed that when the original code was submitted. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
