Description of problem: The f71805f hwmon kernel driver passes '&sio_data' as the second argument to platform_device_add_data(). This is wrong. It should be passing 'sio_data', without the '&'. This problem was found by code inspection after determining the cause behind the problem reported by BZ 559950. There are two other BZs that also report problems caused by this very same issue (BZs 557172 and 560944). The result of this issue is that when one does a modprobe of the driver the system experiences an "Unable to handle kernel paging request at ..." type panic. See the other three BZs for details. I've not been able to find a system within Red Hat that has the necessary chip to run the f71805f driver on, so as to verify that it indeed panics like the other three drivers do. (This is not to say such a system doesn't exist.) Version-Release number of selected component (if applicable): (Assuming this driver is like the other three), kernel-2.6.18-185.el5 How reproducible: (Assuming this driver is like the other three), always. Steps to Reproduce: (Assuming this driver is like the other three), 'modprobe f71805f' Actual results: (Assuming this driver is like the other three), system panic Expected results: No panic
