From 775b64d2b6ca37697de925f70799c710aab5849a Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sat, 12 Jan 2008 20:40:46 +0100 Subject: PM: Acquire device locks on suspend This patch reorganizes the way suspend and resume notifications are sent to drivers. The major changes are that now the PM core acquires every device semaphore before calling the methods, and calls to device_add() during suspends will fail, while calls to device_del() during suspends will block. It also provides a way to safely remove a suspended device with the help of the PM core, by using the device_pm_schedule_removal() callback introduced specifically for this purpose, and updates two drivers (msr and cpuid) that need to use it.

We should set this explicitly every time for each kset. This change is needed so that we can make ksets dynamic, and cleans up one of the odd, undocumented assumption that the kset/kobject/ktype model has. This patch is based on a lot of help from Kay Sievers.

So much so that it's almost impossible to fix with a simple patch, so just comment out the offending registration with the kobject core, and mark the driver as broken. The problem is that the code is trying to register a "raw" struct device, which is not allowed. struct device is only for use within the driver model. This is being done to try to use the firmware layer which wants a struct device. To properly fix this, use something easy, like a platform device, which is a struct device and can be used for this kind of thing.
