    Subject[PATCH v3 0/6] hid: Introduce device groups
    Hi Jiri,

    Here is the third version of the extension to the device-driver
    matching mechanism. AFAICT, there are no outstanding issues. I think
    we are getting close. :-)

    Building on the report fixup patches, this patchset brings a bit of
    transparency to the hid bus, by the addition of device groups. This
    allows a more versatile handling of hid drivers in userland, and
    simplifies the logic in the kernel.

    In particular, there can be one generic module per device group, and
    those modules are handled automatically by udev. Dynamic rebinding of
    drivers is fully supported. For instance, to load a special
    out-of-tree driver instead of the a generic one, simply unbind the
    device and load the new module. One can also keep _all_ generic
    drivers as modules, significantly simplifying the process of adding
    and testing new features.

    And, of course, auto-loading of new multitouch drivers works, since
    that was what triggered this patchset to begin with. :-)

    The second patch contains a simple descriptor scanner that is
    new. The last patch unifies the generic drivers into a single,
    loadable module.


    Henrik Rydberg (6):
    hid: Add device group to modalias
    hid: Scan the device for group info before adding it
    hid: Allow bus wildcard matching
    hid: Create a generic device group
    hid-multitouch: Switch to device groups
    hid: Create a common generic driver
