Heiner Kallweit e0f03e87fc PNP: respect PNP_DRIVER_RES_DO_NOT_CHANGE when detaching ... I have a device (Nuvoton 6779D Super-IO IR RC with nuvoton-cir driver) which works after initial boot but not any longer if I unload and re-load the driver module. Digging into the issue I found that unloading the driver calls pnp_disable_dev although the driver has flag PNP_DRIVER_RES_DO_NOT_CHANGE set. IMHO this is not right. Let's have a look at the call chain when probing a device: pnp_device_probe 1. attaches the device 2. if it's not active and PNP_DRIVER_RES_DO_NOT_CHANGE is not set it gets activated 3. probes driver I think pnp_device_remove should do it in reverse order and also respect PNP_DRIVER_RES_DO_NOT_CHANGE. Therefore: 1. call drivers remove callback 2. if device is active and PNP_DRIVER_RES_DO_NOT_CHANGE is not set disable it 3. detach device The change works for me and sounds logical to me. However I don't know the pnp driver in detail so I might be wrong. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Rafael J.
