  "message": "staging:iio: Make sure a device is only opened once at a time\n\nOur buffer implementation does not support multiple concurrent readers. So we\nhave to ensure that a device is only opened once at a time. So do the same thing\nwe do for the event fd and introduce a per device busy flag. The flag gets set\nwhen opening the device and gets cleared when closing the device. If a open is\nattempted while the busy flag is set we return -EBUSY.\n\nAcked-by: Jonathan Cameron \u003cjic23@kernel.org\u003e\nSigned-off-by: Lars-Peter Clausen \u003clars@metafoo.de\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@suse.de\u003e\n",
