    hwmon: Request the I/O regions in platform drivers · ce7ee4e8
    Jean Delvare authored
    My understanding of the resource management in the Linux 2.6 device
    driver model is that the devices should declare their resources, and
    then when a driver attaches to a device, it should request the
    resources it will be using, so as to mark them busy. This is how the
    PCI and PNP subsystems work, you can clearly see the two levels of
    resources (declaration and request) in /proc/ioports for these
    So I believe that our platform hardware monitoring drivers should
    follow the same logic. At the moment, we only declare the resources
    but we do not request them. This patch adds the I/O region request
    and release calls.
