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.

0aae34fa31 HID: intel-ish-hid: add printf attribute to print_log()
Structure ishtp_device contains a logging function, print_log(), which
formats some of its parameters using vsnprintf(). Add a __printf
attribute to this function field (and to ish_event_tracer()) in order to
detect at compile time issues related to the printf-like formatting.

While at it, make format parameter a const pointer as print_log() is not
supposed to modify it.

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.

6d290391be HID: intel-ish-hid: Fix potential race condition
Although unlikely but it is possible that when a connect or disconnect
request is issued to the firmware, before the response comes, user
terminates the client session. In this case when the response is arrived
there is no matching client instance in the list of currently active
clients. In this case, don't issue call to wake up a waiting client.

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.
