commit dfd0dfb9a7cc04acf93435b440dd34c2ca7b4424 upstream.
The driver overrides error codes returned by platform_get_irq_optional() to -EINVAL for some strange reason, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the proper error codes to platform driver code upwards.
