    PCI/IB: add support for pci driver attribute groups · 92d50fc1
    Greg Kroah-Hartman authored
    Some drivers (specifically the nes IB driver), want to create a lot of
    sysfs driver attributes.  Instead of open-coding the creation and
    removal of these files (and getting it wrong btw), it's a better idea to
    let the driver core handle all of this logic for us.
    
    So add a new field to the pci driver structure, **groups, that allows
    pci drivers to specify an attribute group list it wishes to have created
    when it is registered with the driver core.
    
    Big bonus is now the driver doesn't race with userspace when the sysfs
    files are created vs. when the kobject is announced, so any script/tool
    that actually wanted to use these files will not have to poll waiting
    for them to show up.
