[INPUT] hidinput_connect incorrectly ignored return value from input_register_device Signed-off-by: Dirk Hohndel <redacted>Will applyPlease don't - the fix is completely broken for multi-input devices - if 2nd device fails to register we bail out of hidinput_connect and thus never set HID_CLAIMED_INPUT bit. So when we disconnect device we never call hidinput_disconnect and who knows what will happen after that. hidinput_connect() should properly unwind already registered devices after failure.
Then the existing code to handle hidinput and input_dev allocation failure probably also wants fixing... Dirk's patch was largely following the same logic. Jeff
