tests have shown that output reports use hid_hw_output_report().

hid_out_raw_report is going to be obsoleted as it is not part of the
unified HID low level transport documentation
(Documentation/hid/hid-transport.txt)
hid_output_raw_report(hdev, buf, sizeof(buf), HID_FEATURE_REPORT);
is strictly equivalent to:
hid_hw_raw_request(hdev, buf[0], buf, sizeof(buf),
HID_FEATURE_REPORT, HID_REQ_SET_REPORT);
Then replace buf[0] by the appropriate define.
So use the new api.

Both cp2112_read_req() and cp2112_write_req() are returning negative
value in cases of error, but cp2112_xfer() is storing the return
value into unsigned size_t-typed 'count'.
Fix this by making 'count' signed type.

Commit cafebc0 ("HID: remove hid_get_raw_report in struct hid_device")
obsoletes the use of hdev->hid_get_raw_report(), as calling
hid_hw_raw_request() is functionally equivalent.
Convert cp2112 to use this notation.

This patch adds support for the Silicon Labs CP2112 "Single-Chip HID USB to
SMBus Master Bridge."
This is a HID device driver which registers as an i2c adapter and gpiochip to
expose these functions of the CP2112. The customizable USB descriptor fields
are exposed as sysfs attributes. The SMBus byte-read, byte-data-read/write,
and word-data-read transfer modes have been tested by talking to an i2c
sensor. The GPIO functions and USB descriptor field programming have also
been tested.
