      "message": "HID: uhid: implement feature requests\n\nHID standard allows sending a feature request to the device which is\nanswered by an HID report. uhid implements this by sending a UHID_FEATURE\nevent to user-space which then must answer with UHID_FEATURE_ANSWER. If it\ndoesn\u0027t do this in a timely manner, the request is discarded silently.\n\nWe serialize the feature requests, that is, there is always only a single\nactive feature-request sent to user-space, other requests have to wait.\nHIDP and USB-HID do it the same way.\n\nBecause we discard feature-requests silently, we must make sure to match\na response to the corresponding request. We use sequence-IDs for this so\nuser-space must copy the ID from the request into the answer.\nFeature-answers are ignored if they do not contain the same ID as the\ncurrently pending feature request.\n\nInternally, we must make sure that feature-requests are synchronized with\nUHID_DESTROY and close() events. We must not dead-lock when closing the\nHID device, either, so we have to use separate locks.\n\nSigned-off-by: David Herrmann \u003cdh.herrmann@googlemail.com\u003e\nSigned-off-by: Jiri Kosina \u003cjkosina@suse.cz\u003e\n"
