[ Upstream commit 0306988789d9d91a18ff70bd2bf165d3ae0ef1dd ]
The driver can run without an interrupt so if devm_request_threaded_irq() failed, the probe() just carried on. But if this was EPROBE_DEFER the driver would continue without an interrupt instead of deferring to wait for the interrupt to become available.
