Greg Kroah-Hartman 480104b778 hid: intel-ish-hid: use dev_groups and not dev_attrs for bus_type
The dev_attrs field has long been "depreciated" and is finally being
removed, so move the driver to use the "correct" dev_groups field
instead for struct bus_type.

Bhumika Goyal 12be9f7b58 HID: intel-ish-hid: constify device_type structure
Declare device_type structure as const as it is only stored in the
type field of a device structure. This field is of type const, so add
const to the declaration of device_type structure.

Rasmus Villemoes 608ad1848b HID: intel_ish-hid: use %pUL for uuid formatting
We have the %pU printf extension for doing exactly this. Saves some
.text, and is likely also a little faster.

Srinivas Pandruvada 3703f53b99 HID: intel_ish-hid: ISH Transport layer
The ISH transport layer (ishtp) is a bi-directional protocol implemented
on the top of PCI based inter processor communication layer. This layer
offers:
- Connection management
- Flow control with the firmware
- Multiple client sessions
- Client message transfer
- Client message reception
- DMA for RX and TX for fast data transfer

Refer to Documentation/hid/intel-ish-hid.txt for
overview of the functionality implemented in this layer.
