1aaba11da9 driver core: class: remove module * from class_create()
The module pointer in class_create() never actually did anything, and it
shouldn't have been requred to be set as a parameter even if it did
something.  So just remove it and fix up all callers of the function in
the kernel tree at the same time.

93020953d0 HID: check for valid USB device for many HID drivers
Many HID drivers assume that the HID device assigned to them is a USB
device as that was the only way HID devices used to be able to be
created in Linux.  However, with the additional ways that HID devices
can be created for many different bus types, that is no longer true, so
properly check that we have a USB device associated with the HID device
before allowing a driver that makes this assumption to claim it.

Valo and Kone were 1st generation
Arvo was externaly developed and lies in the middle
All others until now are considered 2nd generation

901e64dbdb HID: roccat: fix NULL pointer dereference, add range checks
On rare occassions raw events can be triggered before drvdata gets set up
which leads to NULL pointer dereferences. This was only observed with pyra on
2.6.39, but is fixed for all devices now to play it save.
kovaplus returned wrong actual values when profile change was initiated from host.
Added range checks for setting actual profile on all devices.

5772f63613 HID: roccat: Introduce module hid-roccat-common
Module hid-roccat-common contains functions used by roccat device driver
modules to reduce code duplication.
At the moment it contains just two wrapper methods for usb_control_msg
that ensure that the buffer used for transfer is dma capable which wasn't
the case before.
The kconfig option is not visible to the user but will be selected by the
device specific drivers.
