Subject: [PATCH 3.4 020/134] HID: fix return value of hidraw_report_event() when !CONFIG_HIDRAW

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jiri Kosina <jkosina@...e.cz>

commit d6d7c873529abd622897cad5e36f1fd7d82f5110 upstream.

Commit b6787242f327 ("HID: hidraw: add proper error handling to raw event
reporting") forgot to update the static inline version of
hidraw_report_event() for the case when CONFIG_HIDRAW is unset. Fix that
up.
