HID: uhid: Add UHID_CREATE2 + UHID_INPUT2

2014-04-01T16:27:33+00:00

UHID_CREATE2:
HID report descriptor data (rd_data) is an array in struct uhid_create2_req,
instead of a pointer. Enables use from languages that don't support pointers,
e.g. Python.

UHID_INPUT2:
Data array is the last field of struct uhid_input2_req. Enables userspace to
write only the required bytes to kernel (ev.type + ev.u.input2.size + the part
of the data array that matters), instead of the entire struct uhid_input2_req.

Note:
UHID_CREATE2 increases the total size of struct uhid_event slightly, thus
increasing the size of messages that are queued for userspace. However, this
won't affect the userspace processing of these events.

HID: make .raw_request mandatory

2014-02-24T16:23:15+00:00

SET_REPORT and GET_REPORT are mandatory in the HID specification.
Make the corresponding API in hid-core mandatory too, which removes the
need to test against it in some various places.

HID: uhid: use generic hidinput_input_event()

2013-07-31T08:33:05+00:00

HID core provides the same functionality and can convert the input event
to a raw output report. We can thus drop UHID_OUTPUT_EV and rely on the
mandatory UHID_OUTPUT.

User-space wasn't able to do anything with UHID_OUTPUT_EV, anyway. They
don't have access to the report fields.
